How to Set the Characteristics of
the Trigger Output
The TRIGGER OUTPUT connector of the central clock module can be
used to inform other instruments upon an event. This event can be:
• Start of a data block within the overall test sequence
•
An event detected by the system (see “Event Handling Principles” on
page 45 ).
To set the trigger characteristics:
1
Open the Parameter Editor for the master clock module (see “How to
Start the Parameter Editor for Global Parameters” on page 85 ).
The Clock Reference window appears.
2
Click the Trigger Output tab.
Figure 30 Trigger Output Configuration Window
3
Set the voltages and output impedance.
4 Select the Mode.
–
Clock Generator : generates a clock signal derived from the system
clock.
–
Sequencer : Generates a transition from high to low or vice versa.
5 Set the delay, if desired. The delay refers to the system clock.
6
Frequency Multiplier is only available in Clock Generator mode. You
can choose one of the factors from the list. The list shows the FMR (see
“How to Set the System Clock Parameters” on page 88 ).
