Trigger Holdoff
Defines the minimum time (in seconds) that must pass between two trigger events.
Trigger events that occur during the holdoff time are ignored.
For more information, see "Trigger Holdoff" on page 479.
Remote command:
TRIGger[:SEQuence]:IFPower:HOLDoff
on page 1050
Slope
For all trigger sources except time, you can define whether triggering occurs when the
signal rises to the trigger level or falls down to it.
For gated measurements in "Edge" mode, the slope also defines whether the gate
starts on a falling or rising edge.
Remote command:
TRIGger[:SEQuence]:SLOPe

8.6.1.3 How to Determine the Required Trigger/Gate Parameters
1. In the "Trigger And Gate" dialog box, switch on "Show Preview".
A zero span measurement for the currently defined center frequency is displayed.
2. Set the "Frequency", "RBW" and "Sweep Time" such that the relevant part of the
signal is displayed, for example a complete burst.
3. Determine the parameters you want to use to define the trigger and gate conditions
from the preview diagram, for example:
● the length of a burst or slot
● the upper or lower power level of a pulse
● the maximum noise level
● the power level or time at which a certain incident occurs
4. Try out different trigger and gate settings as described in How to Configure a Trig-
gered Measurement and How to Configure a Gated Measurement , then select
"Update Main Diagram" to see the effect of the current settings on the main mea-
surement in the background.
5. If the results are as expected, close the dialog box to keep the changes perma-
nently. Otherwise, correct the settings as necessary.
8.6.1.4 How to Configure a Triggered Measurement
To define a time trigger:
1. In the "Trigger And Gate" dialog box, define the "Trigger Source" = "Time".
2. Define the "Repetition Interval": the time after which a new measurement is started.
