Frequency Counter - Period Measurement (msec)

Controls: Options Menu >> Frequency Counter >> msec
Macros: FcountMode=msec, Freq, Total

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.

You can use the Min/Max buttons at any time to see the minimum and maximum millisecond values since the last Reset.

Macro Notes:

FcountMode=msec or FcountMode=2 sets the Frequency Counter to msec mode. See Macro Notes under Frequency Counter - Hertz Measurement for the complete list of mode names and numbers.

Freq is an internal variable that holds the current Frequency Counter readout value, dependent on the chosen mode (Hz, RPM, msec, Total, or SpecTot). You can assign it to a variable such as F via F=Freq, or you can display it via Msg=Freq, or use it directly in an expression.

Total holds the count of total cycles counted since the last Reset, valid during Hz, RPM, or msec modes. This allows macros to get the Total value even when these other modes are active. Note that this does not work in SpecTot mode.
