The Applied Surroundings of the Power Supply

At present, the power supply has a wide application. We need to know the suitable occasion and surrounding which need the power supply device. Here are some instrument for the power supply.
The power supply needs to be installed in the aeration-dry indoor area, and keep away from the noxious gas such as acid and alkali. Because the noxious gas may corrode the electrical elements. It better to have doors in front and behind the power supply device and keep a distance about 800mm with the wall or other facility. The surrounding temperature should among the －10℃ to 45℃. And the relative humidity should be less than 90%.

The Detection Tips of the Programmable DC Power Supply

When we operate the electronic power facility, we need to pay more attention to the safety problem, so when we install the programmable DC power supply we need to know the environment and device explanation. Here are the detection tips of the programmable DC power supply.
1.Open the outer packing, check the attached system photo album, specification, inspection sheet, certification of quality.
2.Whether there are terrible damage condition during the transportational process. If there are damaged parts, we need to handle it in time.
3.If dismount the programmable DC power supply in the low temperature, it may appear the coagulate. We need to dry it before we use it.

The Features and Characteristics of the Programmable DC Power Supplies

The programmable DC power supplies has the features of high stability, lowest noise, low drifting linear structure. The high precision programmable DC power supplies voltage and current are 1mV/10mA and also with the power measurement display function.
The main characteristics of the programmable DC power supplies:
The five type of the voltage output can be suitable for the power requirement in wide range.
It can provide high quality test data.
High output resolution ratio and test resolution, 1mV and 0.1mA, and they can be used to test the circuit and implement in low power.
GPIB and USB standard interface which is easy to realize automatic control.

What’s the Spectrum Analyzer Working Principle？

The structure of spectrum analyzer seems like the oscilloscope which is used for the time domain. There are many function control buttons on the board of the spectrum analyzer. As the adjustment and control of the system control, there are real time spectrum analyzer and scan tune spectrum analyzer. The function of the real time spectrum analyzer is to show the signal amplitude of the frequency domain at the same time. Its working time is as to different frequency signal there are different filters, then send the signal to the CRT screen through the multitask scanning machine. The advantages is that it can show the moment reaction, while the disadvantages is the high cost and the performance is limited by the frequency wide range.

The Four Types of Signal Generator

According to the different signal wave, there are four types of signal generator:
1.Sinusoidal signal generator. It is mainly used to measure frequency characteristic, non-liner distortion, gain and sensitivity of circuit and system. According to different performance and application, the signal generator can be divided into the low frequency signal generator (20Hz-10Hz), high frequency signal generator (100kHz-300kHz), microwave signal generator, sweep frequency and cell-type signal generator, frequency synthesis pattern signal generator.
2.Function signal generator can generate some certain periodicity function wave form signal. It can be applied in the other non-electric measurement field.
3.Pulse signal generator, which can generator the adjustable width, range and frequency signal. It can be used to test the systematic transient response or analog signal.
4.Random signal generator. It includes the noise signal generator and pseudo random signal.

The Main Features of the Programmable DC Power Supplies

The advantages of the programmable DC power supplies are high stability, the lowest noise, low drifting liner structure. High precious programmable DC power supplier has the power measurement and compensation function.
The programmable DC power supplier has the following features:
High stability, lowest noise, low drifting liner structure;
Constant voltage, current working pattern;
The panel function is easy to operate, constant voltage and current output;
Big size LED display;
High resolution of the voltage and current;
Voltage and current time function set, continuous output in different wave;
High speed programmable DC power supplier.

What’s the spectrum analyzer?

Spectrum analyzer is used to study signal distortion, modulation, spectral purity, frequency measurement stability and inter modulation distortion signal parameters. It also can be used to measure some parameters of amplifier and filter circuitry, which is a versatile electronic measuring instruments. It is also called frequency domain oscilloscope, analyze oscilloscope, harmonic analyzer, etc.
Modern spectrum analyzers can display the results of the analysis in analog or digital mode. If the interior of the instrument uses digital circuits and microprocessors, it will have storage and computing functions; it is easy to constitute a test system with the configuration standard interface.

What's the power supply?

Power supply, also known as voltage regulator. With the development of electronic technology, especially after the application of computer technology to various industrial, scientific fields. Various electronic devices require a stable power supply, power supply can not meet the needs. So power supply appears to solve this a problem.

Commonly used AC power supply have:
1.Ferroresonance exchange AC regulator which consist of the saturable reactors and the corresponding capacitors, having constant voltage characteristics.
2.AC magnetic amplifier regulator which is to cascade the magnetic amplifier and auto transformer, then electronic circuit changes the impedance of the magnetic amplifier to stabilize the output voltage.
3.Sliding exchange AC regulator. By changing the position of the contact slide transformer output voltage stability.
4.AC induction regulator. By changing the transformer secondary, primary voltage phase difference, the output AC voltage stability.
5. SCR exchange AC regulator. Thyristor is used as power adjustment element. High stability, fast response and no noise. While it will cause interference for communications equipment and electronic devices.
