Frequently asked questions
What is a frequency response analyzer used for?
It measures how gain and phase of a circuit change across frequency, which is used for characterising filters and amplifiers, for example by plotting a Bode diagram.
How can I use the signal generator function?
Use it to output test waveforms into a circuit or device under test, for example a sine or square signal to check an amplifier, filter or digital input.
