Trigger Frequency Counter
Signal Source Pulse Width or Edge Trigger modes: all available trigger sources
The Frequency Counter measures trigger source at all times, including when the oscilloscope acquisition is
halted due to changes in the run status, or acquisition of a single shot event has completed.
Pulse Width Trigger mode: The oscilloscope counts pulses of signifi cant magnitude inside t he 250 ms
measurement window that qualify as triggerable events, such as narrow pulses in a PW M pulse train if set to <
mode and the width is set to a relatively small time.
Edge Trigger mode: The oscilloscope counts all edges of sufficient magnitude and correct pol ari ty.
Video Trigger mode: The Frequency Counter does not operate.
