Remote Control Reference
4-9
Send a wait command *WAI to ensure synchronization once the bus source is selected.
When commanding *WAI, the power supply will wait for all pending operations to finish
before executing other additional commands. For example, the command, TRIG:SOUR
BUS; *TRG; *WAI; *TRG; *WAI guarantees that the first trigger is accepted and will be
executed before the second trigger is recognized.
Use the operation complete query (*OPC?) or the operation complete (*OPC) command
to generate signal when the last operation is finished. Commanding *OPC? will return 1 to
the output buffer when the last operation is finished. Commanding *OPC will set the OPC
bit 0 in the Standard Event register when the operation is finished.
Immediate Triggering:
Send TRIG:SOUR IMM to select the immediate trigger source.
After selecting IMMediate as a trigger source, INITiate immediately transfers the
VOLT:TRIG or CURR:TRIG value to the VOLT or CURR value. All delay will be ignored.
4.2.2.2 Triggering Command Description
For new users, please read the command description carefully before commanding.
Incorrectly commanding the supply will result in no reaction.
INITiate
If the trigger source is IMMEDIATE, this command complete one full trigger cycle. If the trigger
source is BUS, this command initiates the trigger system.
TRIGger:DELay {<seconds>|MINimum|MAXimum}
This command is used to set the time delay between the detection of an event on the
specified trigger source and the start of any corresponding trigger action on the output. Select
from 0 to 3600 seconds, i.e. MIN = 0 seconds, and MAX = 3600 seconds. At *RST, the value
is set to 0 seconds.
TRIGger:DELay? [MINimum|MAXimum]
This query command is used to query the trigger delay.
TRIGger:SOURce {BUS|IMMediate}
This command is used to select the trigger source of the power supply. Either a bus trigger or
an internal immediate trigger will be accepted. At *RST, the bus trigger source is selected.
TRIGger:SOURce?
This query command is used to query the present trigger source, such as BUS or IMM.
*TRG
This command is used to generate a trigger to the trigger subsystem that has selected a bus
trigger as its source.
4.2.3 Output Control Commands
This section provides information about commands for multiple output control and output
sequence.
