Frequency Counter - Period Measurement (msec)

Controls: Options Menu >> Frequency Counter >> msec
Macro: FcountMode=msec

When this button is active the large Frequency Counter readout shows the period of the Trigger Source in milliseconds. In every other respect it is used like the Hertz measurement option.

If no triggers are detected, or if Trigger is not active, 'No Trig' appears instead of a msec period value.

Applications:

Frequency response

Distortion measurement

Speech and music

Microphone calibration

Loudspeaker test

Musical instrument tuning
