Have you ever asked yourself how many cable there is in this hank?
Or how to check whether the cable conforms to the specification or not ?
Latest firmware updates for AA-55 ZOOM and AA-230 ZOOM analyzers have new boombastic features: Stub tuner and Velocity
factor calculator.
The former designed to quickly measure half- and a quarter wave resonant frequencies.
The latter is to measure the cable chunk length or velocity factor value.
All you need to get such functionality is just update firmware.
