Correct use of spectrum analyzer

Spectrum analyzer has a time-domain test method, generally not used, spectrum analyzer, when the SPAN is set to 0, the spectrum analyzer will become a power change chart with time, set the method for SPAN-ZERO SPAN.

When this method is tested, it is necessary to know the signal bandwidth first, because the time domain shows the power of the signal within a certain bandwidth, and the spectrum analyzer can directly test the bandwidth of the signal.

The power of the signal time is the transmit power, the time period of no signal power indicating the state of being in or out of the signal. When this method is tested, you can also change the detection mode to RMS and set it in the same method.

We can also supply the high quality signal generators, digital multimeters etc. If you need, welcome to contact us.
