Immediate Triggering (TRIG:SOUR IMM)

TRIG:SOUR IMM sets immediate (internal) triggering. The scan list is automatically advanced. This is the default trigger mode.

External Trigger (TRIG)

TRIG:SOUR EXT sets external triggering. The trigger source is a (user supplied) input to the Event In port. Use a +5V negative-going pulse to trigger.

With two or more switchboxes in a mainframe, the first switchbox set for EXT trigger keeps the trigger resource until the switchbox source is changed to BUS, HOLD, or IMM.

 

Trigger Hold (TRIG:SOUR HOLD)

 

 

 

TRIG:SOUR HOLD prevents execution

 

 

 

of triggers until trigger source is changed.

 

Advance Scan (TRIG)

 

Can use TRIG command to trigger a

 

 

 

 

 

switchbox set to TRIG:SOUR HOLD.

 

Can use TRIG command to ad-

 

 

 

 

 

 

 

 

 

 

 

 

vance the scan list when switch-

 

 

 

 

 

 

 

 

 

 

 

 

box is in TRIG:SOUR HOLD or

 

 

 

 

 

 

TRIG:SOUR BUS. For either

 

 

 

 

 

 

trigger source, the scan list

 

 

 

 

 

 

 

 

 

 

 

 

advances one channel per

 

 

 

 

 

 

 

 

 

 

 

 

TRIG command.

 

 

 

 

 

 

 

Bus Triggering (TRIG:SOUR BUS)

TRIG:SOUR BUS defines trigger source as a *TRG or GET command executed over the HP-IB. With TRIG:SOUR BUS, the scan list is advanced for each *TRG or GET command received.

Enabling Trig Out Port (OUTP ON)

The Trig Out port is shared by all instruments in the mainframe. With the port enabled (with OUTP ON), it generates an output trigger after each channel closure for ANY switchbox in the mainframe. The Trig Out port outputs a +5V negative-going pulse.
