Delay
Selection of edge trigger with delay
The delay is triggered by the auxiliary source.
Effective triggering occurs after the end of the delay on the next event from the
main source.
Trigger delay 35.2µs Adjustment with the stylus using the setting scroll bar to choose the
required delay value.
Double-tapping in this field displays a virtual numeric keypad which can be used
to directly input the value.
Holdoff 108ns Adjustment with the stylus using the setting scroll bar, allows
disabling of the trigger for a predefined period and, among other
things, stabilization of the trigger on pulse trains.
Double-tapping in this field displays a virtual numeric keypad which can be used
to directly input the value.
Auxiliarysource
selects the channel as the trigger source.
Coupling selects the filter for the auxiliary trigger source:
AC AC coupling (10 Hz to 200 MHz):
blocks the DC component of the signal
DC DC coupling (0 to 200 MHz):
allows the entire signal through
LF Reject Rejection of source signal frequencies < 10 kHz:
facilitates observation of signals with a DC
component or an unwanted low frequency
HF Reject Rejection of source signal frequencies > 10 kHz:
facilitates observation of signals with high-frequency noise
Level
2.04V Adjustment of the trigger level with the stylus on the scroll bar.
Edge
selects the edge for the auxiliary trigger source:
+ ascending trigger edge
- descending trigger edge
Noise reject No: hysteresis
≈
0.5 div.
Yes: introduces a hysteresis of
≈
1.5 div.
