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.

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.
