3.23 Trigger subsystem
The Trigger subsystem is made up of a series of commands and subsystems to configure the
three layers of the Trigger Model (see paragraph 2.7 and 3.8 for details). These commands and
subsystems are summarized in Table 3-15.
:INITiate commands
[:IMMediate]
:INITiate[:IMMediate] Take 2002 out of idle
This command takes the Model 2002 out of the idle state. After all programmed operations are
completed, the instrument leaves the trigger layers and returns to the idle state if continuous ini-
tiation is disabled; (see next command).
PRINT #1, "output 16; :init" ' Take 2002 out of idle
:CONTinuous <b>
:INITiate:CONTinuous <b> Control continuous initiation
<b> = 0 or OFF Disable continuous initiation
1 or ON Enable continuous initiation
:CONTinuous? Query continuous initiation
When continuous initiation is selected (ON), the instrument is taken out of the idle state. At the
conclusion of all programmed operations, the instrument returns to Arm Layer 1.
PRINT #1, "output 16; :init:cont on; cont?" ' Enable continuous initiation
PRINT #1, "enter 16" ' Get response from 2002
:ABORt
:ABORt Abort operation
When this action command is sent, the Model 2002 aborts operation and returns to the top of
the Trigger Model. If continuous initiation is disabled, the instrument goes the idle state. If con-
tinuous initiation is enabled, operation continues on into Arm Layer 1.
The abort command resets the source bypasses of the Trigger Model. If scanning, the scan
pointer resets back to the first channel in the scan list.
PRINT #1, "output 16; abor" ' Abort operation
:IMMediate
:ARM[:SEQuence[1]][:LAYer[1]]:IMMediate Bypass arm control source
:ARM[:SEQuence[1]]:LAYer2:IMMediate Bypass scan control source and delay
:TRIGger:[:SEQuence[1]]:IMMediate Bypass measure control source and delay
