Electronic charge and its application in the Test Equipment

The electronic measuring instrument is widely used. Take the DC electronic load as an example, is widely applied in the field of LED driver, testing the power module, the production of chargers and UPS. It has become essential test equipment in these areas.
Electronic charge has reached the charging function for Measurement & Analysis Instruments, and the output port is in accordance with Ohm’s law. Specifically, the Hipot tester is a device which causes the tube to have the power dissipation and consumption of energy by means of controlling the internal power MOSFET device or driver transistor flow. Generally include electronic charge constant current, constant voltage, constant resistance, constant power, short circuit, the dynamic load and a variety of modes, and can simulate various load conditions.

Electronic charge as a professional team to test power, is flexible to operate. It is convenient for users to discuss various date for full software GUI. Moreover, the application can be integrated not only the automatic test system with the acquisition of high-speed data, but can also protect equipment fully tested.
Examples of electron charge application are as follows.
First component manufacturers such as LCD computer can use the electronic charge to achieve its internal power supply module testing and aging.
Second feed manufacturers and LED switching the electronic charge can be used to achieve the stability test of the power supply, the stability of load, the output voltage regulation and transient characteristic parameters. (Multi-output power supply can be used for fixing the combined test.
Thirdly, the application of the manufacturers and the charger adapter are as follows. It is important to test the ability to regulate output voltage and current as it can ensure the correct supply and battery charging equipment. You can make a routine performance test in CC and CR modes. You can also use the functions of the OCP and short to test the movement of product protection. Adjustment time, load, etc. charging time can be adjusted charging time of the electronic charge.
The electronic charge is more widely used in the manufacture of electronic products and application equipment testing area. Now we can illustrate the examples. In the hot spot test solar panel, the electronic charge is often used. in the test cell temperature of the hot zone street sign, put the panel non-opaque, outdoors and exposed to the radiation source at 700 W • m-2 at least. Test performance imp IV and current at the point of maximum power. Or that the panel is short, place the panel in the 700 block W • m-2 at least. Use infrared photography to measure the top cell, and record temperatures. Under the same radiation source, the change of the radiation is less than 5% in the period. Connect the positive and negative electronic charge to the panel.
DC electrical safety tester includes constant current, constant voltage, constant resistance and constant power of the four test modes. Overall, we select the constant current test, as it provides inputs to different components of the operating current. The aim is to test the hot spot cell under the current work differently, record the hot situation. So easy to set temperature requirements of solar panel hot spot. At the same time, but also facilitates the measurement of a variety of hot spots in the continuous radiation in the room.

The different types of electronic test equipment

In order to measure the electrical power used, it takes a power monitor. Power meters and panel meters very useful, too. One of the pillars of electronic engineering is an electronic test equipment, also known as testgear or table. Electronic test equipment is essential for measuring and sending signals and detect the responses of electronic devices being tested for functionality and quality. When there is a failure in signal reception or generation of the response, which could mean that the device under test (DUT) has a defect. By using electronic test equipment, this defect is detected and repaired, even before the device under test is used by the client. Therefore, the electronic test equipment is essential for solving problems effectively and efficiently.
Types of Electronic Test Equipment
The basic equipment for electronic evidence including measuring devices, sources of stimulus, response analyzers and connectors. Power supplies, digital pulse generators, pattern generators and signal generators are a source of encouragement. Ammeter, ohmmeter and voltmeter, as indicated by their names, measure the resistance of current and voltage respectively. These measures can also be recorded by a single device called a multimeter. A multimeter can be a volt-ohm-milliammeter (VOM) and either a digital multimeter (DMM). The analysis of the response of the DUT is performed by detecting changes in resistance of current and voltage in time by an oscilloscope or changes in frequency by the frequency counter. The probes are used to connect these devices to the device under test.
Electronic Evidence
Panel meters are devices that measure and display information from another electronic test equipment. There are two types: the panel meter analog and digital panel meter.
The analog panel meter has two components: a sphere and a moving needle. The analog meter band strap uses a needle and two metal strips to measure current (DC). The pivot and jewel analog meters using a coil and a pointer, a steel and two jewel bearings for measuring alternating current (AC).
The digital meter is considered more accurate than the analog panel meter. Can be measured and have different electrical data such as input signal, voltage, current and frequency. Digital meters have multiple LEDs that represent alphanumeric characters. This makes reading easier and more accurate measurements compared to the present of a needle or pointer analog panel meters. In addition, digital meters can receive and display multiple entries at once. You can display bar graphs, perform calculations and data logging with multifunction capability, not surprisingly, are replacing their analog counterparts, both the market and industry.
Digital panel meters also have options for alarm, calibration options and controls on / off switch that allows the user to start or stop a test of a circuit. Today, many of these devices can now connect to a computer and Internet for data transfer or storage.
The disadvantages of digital meters is the fact that they are expensive. Cost may be a deterrent to users who are considering moving from analog panel meters digital panel meters away. However, the use of the latter is more profitable in the long term because its use allows for more accurate fault detection and avoids failures of electronic devices.

Thermal management of electronic devices and systems

Thermal resistance of this vision devices are usually cited as the thermal resistance of the output for the case of the semiconductor device. units are c / w. for example, a nominal heat sink 10 C / W will 10c hotter than the surrounding air when dissipates 1 watt of heat. therefore, a heat sink with a low w / w value is more efficient than a heat sink with a high c / w value. thermal time constants thermal mass of a heat sink can be regarded as a (heat storage instead of load) and thermal resistance capacitor as an electrical resistance (which gives a measure of how fast the heat can be dissipated stored .) Together, these two components form an RC circuit with a thermal time constant associated given by the product of R and C. this amount can be used for calculating the heat dissipation capacity of a dynamic device in a manner analogous to the electric case. a specific type of thermal interface material is placed between the heat source and to increase the thermal efficiency), such as a microprocessor chip or other semiconductor power handling to stabilize its temperature through increased thermal mass and heat dissipation (primarily by conduction and convection and to a lesser extent by radiation). device heatsinking main article s: s are widely used in electronics, and have become almost indispensable in modern central processing units. in common use is a metal object in contact with the hot surface of an electronic component, although in most cases, a thin half thermal interface material between the two surfaces. power semiconductor chips and handling are examples of electronic components that need to reduce its temperature by increased thermal mass and heat radiation (mainly by conduction and convection and by radiation to a lesser extent). s have become almost essential to modern integrated circuits such as microprocessors, DSPs, GPUs, and more. a generally consists of a metal structure with one or more flat surfaces to ensure good thermal contact with the components to be cooled, and an array of comb or fin like protrusions to increase surface contact with air, and both the rate of heat dissipation. a is sometimes used in conjunction with a fan to increase the airflow rate on. This maintains a higher temperature gradient replacing heated air faster than you would convection. this is known as a forced air system. CPU fan connected to (or heat sink) is an environment or object that absorbs and dissipates heat from another object using thermal contact (either direct or radiant). s are used in a wide range of applications where efficient heat dissipation is required; Important examples include refrigeration, heat engines and cooling electronic devices. first radial thermal profile and eddies forced convection flow paths (using CFD analysis) pin fin with thermal profile and the convective flow paths dione (using CFD analysis) on a workstation fire test the base plate, where the steel pipe penetrations clearly act to absorb and conduct heat from the furnace through the unexposed side. s function efficiently thermal energy transfer (“hot”) of an object at high temperature to a second object to a lower temperature with a much higher heat capacity. This rapid transfer of thermal energy quickly brings the first object in thermal equilibrium with the second, lowering the temperature of the first object, fulfilling the role of ‘s as a cooling device. an efficient function is based on the rapid transfer of heat energy from the first object, and the second for the object. the most common design of a metal is a device with many fins. high thermal conductivity of metal combined with its large surface area result in the rapid transfer of thermal energy to the surrounding, cooler, air. this is cooled and which is in direct thermal contact with. the use of liquids (eg refrigerant in cooling) and the thermal interface material (in the cooling of electronic devices) ensures good transfer of thermal energy to the. Similarly, a fan can improve the transfer of thermal energy from the air. construction materials and a generally consists of a base with one or more planar surfaces and a comb or as series of ribs to increase the area ‘s surface in contact with air, thereby increasing the heat dissipation capacity. while a is a static object, a fan often helps air flow, providing an increased thereby maintaining a higher temperature gradient replacing the air heated faster than the passive convection only achieves this is known as a system forced air. Ideally, s are made of a good thermal conductor such as silver, gold, copper, or aluminum alloy. copper and aluminum are among the most frequently used material for this purpose within electronic devices. copper (401 W / (mK) at 300 K) is significantly more expensive than aluminum (237 W / (mK) at 300 K), but also is approximately twice as efficient as a thermal conductor. Aluminum has the significant advantage that can be easily formed by extrusion, whereby the complex cross-sections possible. aluminum is much lighter than copper, which offers less mechanical stress on sensitive electronic components. s one made of aluminum with a copper core as a compromise. the surface of the ‘s contact (base) must be flat and smooth to ensure the best thermal contact with the object of cooling need. often a thermally conductive grease is used to ensure optimal thermal contact, such compounds often contain colloidal silver. furthermore, a clamping mechanism, screws, adhesive or thermal maintained firmly against the component, but specifically without pressure that could crush the component. yield performance (including free convection, forced convection-cooled liquid, and any combination thereof) is a function of the material, the geometry and the overall coefficient of heat transfer surface. generally, the thermal efficiency is enhanced by forced convection by increasing the thermal conductivity of materials, increasing the surface area (usually by the addition of extended surfaces, such as fins or metal foam) and increasing the total heat transfer area coefficient (usually by increasing the velocity of fluid, such as the addition of ventilators and pumps. line calculators companies as novel concepts, Inc., can accurately estimate the performance of forced convection. for complex geometries and / os with multiple materials and / os with various fluids, computational fluid dynamics (CFD) is recommended (see chart above). used in the PC market of electronics, due to recent advances technology and the public interest, the retail market has reached its highest point. in the 2000s, processors were produced and emitted more heat than the above requirements, the escalation of quality refrigeration systems. overclocking has always meaning a greater need for cooling, and hot chips inherently mean more problems for the enthusiast. s efficient are vital to overclocked computer systems because the higher rate of cooling a microprocessor, the faster the computer can function without the instability, generally, faster operation leads to higher performance. many companies compete to offer the best for overclocking enthusiasts PC. major aftermarket manufacturers include: cool aero, Foxconn, Thermalright, Thermaltake, Swiftech , and Zalman. s in the welding time are sometimes used while soldering circuit boards, preventing excessive heat damage sensitive electronic equipment. in the simplest case, that means grabbing a component part with a clip crocodile clip heavy metal or similar. modern semiconductor devices which are designed to be mounted by reflow soldering, can usually tolerate soldering temperatures without damage. on the other hand, electrical components such as magnetic reed switches can malfunction if exposed to high powered welders, so this practice is still very much in use. recent developments, most recently, sinks, cooling synthetic diamond are being investigated to provide better cooling. Also, some s are constructed of materials Multiple with desirable characteristics such as phase change materials, which can store a large amount of energy due to its heat of fusion. air convection cooling this term describes cooling device by the convection currents of hot air being allowed to escape the confines of the component to be replaced with cooler air. since the hot air rises normally, this method usually requires ventilation in the top or side of the housing to be effective. forced air cooling, if more in a forced air system which is pumped out (due to an imbalance in the number of fans), this is known as a “positive” air flow, as the pressure inside the unit is higher than outside. a flow balanced or neutral air is the most efficient, although there is a slight positive air flow in less accumulation of dust. a heat pipe heat sink (aluminum) which incorporates a heat pipe (copper) a heat pipe is a mechanism heat transfer that can carry large amounts of heat with a very small difference in temperature between the hot and cold interfaces. a typical heat pipe comprises a hollow sealed tube made of a thermoconductive metal such as copper or aluminum. the tube contains a relatively small amount of a “working fluid” or coolant (such as water, ethanol or mercury) with the rest of the tube is filled with the vapor phase of the working fluid, all the other gases being excluded. the advantage of tubes Heat is its high efficiency of heat transfer. are actually more “conductor” of a copper bar equivalent cross section. plates Peltier Peltier cooling plates (pronounced / pltye /) cooling to take advantage of what is known as the Peltier effect to create a flow of heat between the junction of two different types of materials. this effect is commonly used to cool Electronic Components & Supplies and small instruments. no moving parts and a device requires no maintenance. due to the relatively low efficiency, thermoelectric cooling is generally only used in environments where nature in the solid state is greater than the poor efficiency. thermoelectric junctions are generally only 10% as efficient as the ideal refrigerator (Carnot cycle), compared 40% achieved by conventional compression cycle. synthetic air jet cooling a synthetic jet is produced by a continuous flow of vortices formed by the alternation of short ejection and suction of air through an opening such that the net mass flow is zero. a unique feature is that these jets are formed entirely from the working fluid flow system in which are implanted may produce a net momentum flow injection system massless Net the system. synthetic jet air suction have no moving parts and therefore are free of maintenance. due to high heat transfer coefficients, high reliability, together with lower flow rates generally suction synthesis air jet is generally used in the chip and system level rather than cooling. However, depending on the size and complexity of the systems that can be used for both sometimes. see also electronics thermal resistance tube heat Radiator Cooling External links IT assets which is cooling thermal management?

Tektronix ‘comprehensive coverage of University Laboratory echelon demand

As we all know, significant laboratory of electrical engineering education, the students hands-on and practical ability is often not from textbooks, but in the laboratory. But in fact, the University Laboratory of educational resources are very scarce. In the past decade, many colleges and universities because of enrollment led to surge in the number of students, limited equipment procurement budget, the laboratory scale far to keep up with the rate of increase of the number of students. On the other hand, the laboratory level of impact the reputation and the reputation of the school. Colleges and universities need to have the best equipment to attract the most potential engineering students, and lay the foundation for them to enhance future employment or engage in innovative research capability.

Meanwhile, the curriculum design of today’s colleges and universities are also the times, become more complex, to ensure that students have learned to the community. For example, today’s engineers need to test and debug more complex embedded design and RF design, so the university laboratory equipment should meet the basic requirements.

“Tektronix is, we hope to help all schools to deal with these challenges. Tektronix Since entering the Chinese market, has attached great importance to cooperation with domestic educational institutions. A leading manufacturer of measurement as a global test of a set up for over 65 years, Thailand g has a wide range of product line, can meet basis from undergraduate course to the core laboratory research and development laboratory configuration requirements of all levels. “Tektronix Greater China retail channel sales manager Chen Ying rain said.

Rich to meet the education market echelon demand

Chen Ying rain, said, Tektronix for undergraduate electronics laboratory product line is divided into three categories. First, is the basic teaching of laboratory testing equipment, mainly for the second grade basic knowledge or basic experimental grasp. All aspects of the testing requirements are not particularly high, more emphasis on a simple test, observe the waveform. The second category is the senior teaching to help high school students to obtain a more complex test methods in a more complex curriculum. The third category is more for a number of university research and development and disciplinary focus of the laboratory test equipment.

For the construction of basic laboratory, usually and ultimately four – oscilloscope, signal source, a multimeter and power, Tektronix, at least three-piece in an absolutely leading position in this field, one is the oscilloscope, such as the latest TDS1000C-EDU basis oscilloscope, TDS2000C series, the TDS3000C series, as well as supporting a variety of voltage probes, current probes, high voltage differential probe, AFG3000 series arbitrary waveform generator (source), and the the DMM4000 series desktop multimeter, they can carry out the validation experiments may also cover the demand for innovative experiments.

With undergraduate studies in depth or to the graduate level, many students no longer satisfied with the contents of the textbook, the teacher will not meet the students only with the textbook to do experiments, do not create their own. Tektronix also offers a range of test equipment for the building needs of the senior teaching and research and development laboratories. This stage of the experiment not only to look at the signal, but also to analyze analog, digital, or serial data and other signals, and higher efficiency of debugging. Tektronix MSO/DPO2000 Series, the MSO/DPO3000 Series, the MSO/DPO4000B Series desktop oscilloscopes and AFG3000 Series signal generator provides a cost-effective choice.

As noted above, Tektronix, a class of the education market test products aimed at university professors or researchers and disciplines Key Laboratory.

Construction of basic laboratory, performance and quality ranked first

University laboratory, a rich selection of products is not enough, high quality and durability is also very important. School students and engineers, they just may not have received too much professional training, master the rules of operation to deploy, easy to damage the equipment, which will be an additional school maintenance budget.

Southeast University, Electrical and Electronic Experiment Center Director Professor Hu Renjie also said: “From the perspective of our teachers, the requirements of the instrument is reliable, stable and accurate because students often do not know the results before to experiment. Affect the outcome of the reason there are ways to on equipment error may be caused by select components. If the instrument itself result in errors, the student will be confusion on their own experimental results as a school, we should try to rule out the possibility error factors. ”

Tektronix as the world’s leading manufacturer of test and measurement equipment has been said that quality with strong durable, low repair rate, so a wide range of colleges and universities favor.

TDS1000C-EDU: the basis of teaching laboratory building “timely rain”

The new economy of high-quality digital oscilloscope Tektronix in March 2012 TDS1000C-EDU series (starting at just 7830 yuan), can be said that the development of university basic teaching laboratory building under a timely rain.
