Example:
This 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.
Step 2: Enable the following settings:
●
"ARB > Trigger In > External Delay Unit > Time"
●
"ARB > Trigger In > Specified External Delay = 10 us"
Logically, the "Actual External Delay" changes to 10 us.
Step 3:
●
Switch to "ARB > Trigger In > External Delay Unit > Samples".
The value of "ARB > Trigger In > External Delay" is 10 samples.
Receiving and Providing Trigger Signals
In test setups that combine the signal of two or more instruments it is often required
that:
●
The signal generation starts at a defined moment
●
The signal generation starts simultaneously (or with an exactly defined delay) in all
involved instruments.
For information on simultaneous signal generation start in multiple instruments,
see Chapter 8.3, "Generating Time-Aligned Baseband Signals", on page 428.
