Network Analyzer
Combine your DSO101 Oscilloscope and WGM101 Waveform Generator into a Network Analyzer with FREE software.
The purpose of a network analyzer is to determine the amplitude and phase repsonse or transfer function of some electrical network. For example, a network analyzer is useful in measuring the amplitude response of an audio tone control or audio filter. It is possible to make these types of measurements by hand, using the DSO101 oscilloscope and the WGM101 waveform generator. The network analyzer software does the job automatically, and plots the amplitude and phase response against frequency.
