The 1256 may be armed, and a single trigger may be sent, using
the TRIGGER:IMMEDIATE command. The syntax for this
command is:
:TRIGger
[:SEQuence]
:IMMediate
This command is equivalent to the following:
A) Programming the trigger source
B) Arming the 1256 with an INIT:IMMEDIATE command
C) Sending a single trigger on the selected trigger source
This command may be used to execute the next step of a scan list.
The 1256 may be programmed to generate an output trigger pulse
each time a relay operation has been completed. The output
trigger pulse may be placed on the external trigger output found on
the rear panel of the 1256. Refer to Figure 7-1: Using External
Trigger In and External Trigger Out for connector location and
signal information. This trigger pulse may be used to inform other
instruments that the relay(s) have settled, and a new measurement
may take place.
The OUTPUT:TRIGGER command is used to enable or disable
the external trigger line. The syntax for this command is:
:OUTput
:TRIGger
[:STATe] { ON | 1 | OFF | 0 }
Once the trigger output is enabled, it may be disabled by:
A) Deselecting the line, using the "OFF" parameter.
B) Sending the *RST command.
For example, the following commands may be sent.
To enable the external trigger output:
OUTPUT:TRIGGER ON
To disable the external trigger output:
OUTP:TRIG 0
The present destination for the trigger output pulse may be read by
