4.Counting
Qualifier
Selection of triggering on edge with counting of events.
Selection of adjustments on the qualification source
:
100 µs Disabling of triggering for a preset duration and, among other things,
stabilization of triggering on pulse trains.
Pointing to this field opens on the screen a virtual digital keypad for direct entry of the
value.
Counting settings The counting is triggered by the auxiliary source; the main source serves as counting
clock.
Actual triggering occurs on the next trigger event in the main source after the end of
the count:
3 Choice of desired number of events.
Pointing to this field opens on the screen a virtual digital keypad for direct entry of the
value.
Trigger Selection of adjustments on the triggering source :
Selection of the filter of the auxiliary triggering source:
AC AC coupling (10Hz to 300MHz):
blocks the DC component of the signal.
DC DC coupling (0 to 300MHz):
passes the whole signal.
LF Reject Rejection of source signal frequencies < 10kHz:
facilitates the observation of signals having a DC
component or an undesirable low frequency.
HF Reject Rejection of source signal frequencies >10kHz:
facilitates the observation of signals containing high-frequency noise.
