TRIGger:SOURce BUS | EXTernal | HOLD | IMMediate specifies the
trigger source to advance the channel list during scanning.
Parameters
Parameter Name Parameter Type Range of Values
BUS discrete *TRG or GET command
EXTernal discrete “Event In” BNC port
HOLD discrete Hold triggering
IMMediate discrete Immediate triggering
Comments
•
Enabling the Trigger Source: The TRIGger:SOURce command
only selects the trigger source. The INITiate[:IMMediate] command
enables the trigger source.
•
Using the TRIG Command: You can use TRIGger[:IMMediate] to
advance the scan when TRIGger:SOURce HOLD or
TRIGger:SOURce BUS is selected.
•
Using External Trigger Inputs: With TRIGger:SOURce EXTernal
selected, only one switchbox at a time can use the external trigger
input at the HP E1300A/E1301A mainframe “ Event In” BNC port.
The trigger input is assigned to the first switchbox that requested the
external trigger source (with a
TRIGger:SOURce EXTernal
command).
•
Assigning External Trigger: A switchbox assigned with
TRIGger:SOURce EXTernal remains assigned to that source until the
switchbox trigger source is changed to BUS , HOLD , or IMMediate .
When the source is changed, the external trigger source is available
to the next switchbox which requests it (with a
TRIGger:SOURce EXTernal command). If a switchbox requests an
external trigger input already assigned to another switchbox an error
is generated.
•
Using Bus Triggers: To trigger the switchbox with
TRIGger:SOURce BUS selected, use the IEEE 488.2 common
command *TRG or the HP-IB Group Execute Trigger ( GET )
command.
•
Trig Out Port Shared by Switchboxes: See the OUTPut
command.
