We all know that the spectrum analyzer can be applied in many areas and plays a important part. We need to know more about it such as how to use it properly.

The most common spectrum analyzer is the scan tune spectrum analyzer. The modulated local oscillator generate the oscillation frequency with linear variation along time with the scan generator.

?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.
