main source.
Trigger delay
35.2µs Adjustment with the stylus using the setting scroll bar to choose the

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:
+
rising trigger edge
-
falling trigger edge
