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.
