Trig Slope
Controls the trigger polarity. It is set positive to trigger on a rising edge and negative to trigger on a falling
edge.

:TRIGger[:SEQuence]:EXTernal1:SLOPe?
Example TRIG:EXT1:SLOP NEG
Couplings This same slope is used in the Ext1 selection for the trigger source in the Trigger menu and for the
period timer sync source (in the Trigger menu and in the Gate Source menu).

Zero Span Delay Comp On/Off
In zero span, there is a natural delay in the signal path, which comes from the RBW filter. This is usually
desirable, as it allows you to trigger on events and also see those events, because the signal is delayed
from the trigger event. However, in some cases it is desirable to eliminate this delay, so that trigger
events line up exactly with the zero time point in zero span. You can use the Zero Span Delay Comp On/Off
feature to enable or disable zero span delay compensation.
