Triggering system active and ready for events: both LEDs are green
●
Triggering system active and incoming trigger event:
[Trigger A]-LED is red during approximately 0.5

●
Triggering system active and incoming reset event:

The "Trigger Activation" section (top portion of Figure 5-45 ) provides the following:
●
You can activate or deactivate the trigger functionality.
When triggering is active, this state is indicated by the following:
–
The trigger status LEDs next to the BNC connectors are on (green light).
– The top right corner of the user interface displays the "TRG" flag:
When the trigger is active, also be aware of the following additional effects:
–
All module views are hidden
– You cannot switch relays via the Module Operation dialog
– You cannot switch paths via the Path Switching dialog, but only by triggering
– RC Commands (SCPI), which can interfere with the trigger functionality or can
prevent correct triggering, are not executed.
Calling forbidden commands creates an error message, which you can query
by
SYSTem:ERRor
.
The following commands are forbidden:
–
Commands for changing path configurations
– Commands for changing the interconnection configuration
– Switching commands, which change the state of relays or channels, especially
ROUTe:CLOSe
– Querying the switching state of relays or channels by
ROUTe:CLOSe?
is not
supported
However, the commands
*RST
and
SYSTem:PRESet
are permitted and deactivate
the trigger mode.
If you cannot activate the trigger, possible reasons are, for example:
–
Your trigger license has just expired, see "Software Options Overview"
on page 160
– A secondary switch unit does not respond, although it is required for a config-
ured path to be triggered
●
You can send a "Manual Trigger" pulse, if the trigger functionality is enabled and
its configuration is complete.
The "Manual Trigger" button is equivalent with sending a remotely controlled trigger
pulse by
*TRG
or with receiving the next incoming trigger signal at the BNC con-
nector.
The "Manual Trigger" is not available for the
Addressed trigger type.
●
You can send a "Sequence Reset" for the Sequenced trigger, if the trigger func-
tionality is enabled and its configuration is complete.
