Specifying delay and inhibit values
Trigger delay and inhibit values are expressed in the units of the generated signal, e.g.
in samples or symbols. You can also define the exact delay or inhibit period as a time
value, e.g. in seconds.
Trigger delay values t
delay
depend on the instrument hardware. The table illustrates an
exemplary instrument configuration and related t

values in samples (or symbols)
and in seconds.

Example: Trigger delay and ARB clock frequency
The example is based on an ARB signal with 1 MHz clock frequency ("Baseband >
ARB > Clock Frequency = 1 MHz").
Step 1: Enable the following settings:
●
"ARB > Trigger In > Mode > Armed Auto"
●
"ARB > Trigger In > Source > External Global Trigger 1"
●
"ARB > Trigger In > External Delay Unit > Samples"
●
"ARB > Trigger In > External Delay = 100 Samples"
The parameter "Actual External Delay = 100 us" displays the time delay in seconds.
