Source
Frequency counter measures selected trigger source at all times in pulse width and edge mode, including
when oscilloscope acquisition is halted due to changes in run status, or acquisition of a single shot
event has completed.
Frequency counter does NOT measure pulses that do not qualify as legitimate trigger events.
Pulse Width mode: Counts pulses of suf
fi cient magnitude inside the 250 ms measurement window
that qualify as triggerable events (for example, all narrow pulses in a PWM pulse train if set to < mode
and the limit is set to a relatively small number).
Edge Trigger mode: Counts all pulses of suf
fi cient magnitude.
