2.
Delay Time
Sets the time interval during which the instrument waits to start the sweep
operation after the trigger signal that meets the trigger conditions is generated.
You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.

Parameter
Remarks
Default
1 μs
Range
-16.384 s
[1]
to 500 ms
Unit
s, ms, μs, ns, ps
Knob Step
trigger delay/100, Min = 1 μs
Left/Right Arrow Key Step
Up/Down Arrow Key Step
at 1-1.5-2-3-5-7.5 step
Note
[1]
: A negative trigger delay time indicates a pre-trigger.
3.
Power
Sets the trigger level of the IF power trigger. When the signal meets the set
trigger level value, a trigger occurs. When the data source is "CaptureTime", and
the trace format is "Log Mag (dB)" or "Linear Mag", the trace window displays
the trigger level line.
