Triggering Commands
92
To ensure synchronization when the bus source is selected, send the
*WAI
(wait) command. When the
*WAI
command is executed, the power supply
waits for all pending operations to complete before executing any additional
commands. For example, the following command string guarantees that the
first trigger is accepted and is executed before the second trigger is
recognized.
TRIG:SOUR BUS;*TRG;*WAI;*TRG;*WAI
You can use the
*OPC?
(operation complete query) command or the
*OPC
(operation complete) command to signal when the operation is complete.
The
*OPC?
command returns ‘‘1’’ to the output buffer when the operation
is complete. The
*OPC
command sets the ‘‘OPC’’ bit (bit 0) in the Standard
Event register when the operation is complete.
Immediate Triggering
To select the immediate trigger source, send the following command.
TRIG:SOUR IMM
When the
IMMediate
is selected as a trigger source, an
INITiate
command immediately transfers the
VOLT:TRIG
or
CURR:TRIG
value to
VOLT
or
CURR
value. Any delay is ignored.
