​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.

​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.

​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 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.

​According to the different signal wave, there are four types of signal generator:1.Sinusoidal signal generator. 2.Function signal generator can generate some certain periodicity function wave form signal. 3.Pulse signal signal generator.4.Random signal generator.

​The advantages of the programmable DC power supplies is high stability, the lowest noise, low drifting liner structure. High precious programmable DC power supplier has the power measurement and compensation function.
