Difference between spectrum analyzer and signal analyzer

图片
Spectrum analyzer  is often the analysis of the frequency composition of the input signal. The signal analyzer is used to analyze the characteristics of the signal. From the visual display, a spectrum analyzer is shown for each frequency point on line which frequency signal is stronger the higher the bright line. The signal analyzer shows the full waveform of the signal. You can analyze the frequency of the signal, the cycle, the magnitude of the distortion and so on by means of an instrument. Of course, newer analyzers are versatile, called synthetic testers. It can almost do most of the work of measurement.

In electronic testing and measurement, a signal source is usually required to generate only signals that can be supplied from outside. When selecting a  signal generator , consider common features. 1, sampling rate. The sampling rate affects the frequency of the main output signal. 2, memory depth or record length plays an important role in signal fidelity as it determines how many data points can be stored to define a waveform. 3, some signal generators provide a range of features and output functions. In selecting the signal generator, you should also evaluate the standard waveform, modulation function, output amplitude and waveform editing software to ensure that the instrument meets your needs.

Time domain power detection method for spectrum analyzer

图片
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.
