A.16 *TRG — TRIGGER COMMAND
*TRG
Syntax : *TRG
Description: Triggers the power supply to be commanded to preprogrammed values of output current and
voltage.
When the trigger is armed, *TRG generates a trigger signal if TRIG:SOUR is set to BUS and
the WTG bit in Status Operational Condition register (bit 5, Table B-4) is asserted. The trigger is armed
by sending a) INIT:CONT ON to continuously arm the trigger and allow subsequent *TRG commands
to generate the trigger signal or b) if INIT:CONT is set to OFF, sending INIT arms the system and
allows a *TRG to generate a single trigger. If *TRG is received while the trigger is not armed, the trig-
ger is not produced and no error is generated.
The trigger will change the output of the power supply to the output voltage and current levels speci-
fied by VOLT:TRIG and CURR:TRIG commands and clear the WTG bit in the Status Operation Condi-
tion register. If INIT:CONT 1 (ON) has been issued, the trigger subsystem is immediately rearmed for
subsequent triggers, and the WTG bit is again set to 1. *TRG or GET are both addressed commands
(only devices selected as listeners will execute the command). If output is set to OFF, *TRG is ignored.
Related Commands: ABOR, INIT, TRIG, CURR:TRIG, VOLT:TRIG. (See example, Figure A-1.
)
A.17 *TST? — SELF TEST QUERY
*TST?
Syntax : *TST? Returned value: 7 bits coded per Table A-4.
Description: Power Supply test. This query causes the power supply to do a self test and provide the controller
with pass/fail results. A 0 is returned if the unit passes the test. If the unit fails, a number from 1
through 128 is returned to indicate the cause of the error. The test executes each of the subtests even
when any one fails. If any test fails an error code bit is set which is returned to the user. The error
codes returned are listed in Table A-4
A.18 *WAI — WAIT-TO-CONTINUE COMMAND
*WAI
Syntax : *WAI Response:
Description: Causes the power supply to wait until all previously issued commands and queries are com-
plete before executing subsequent commands or queries.
This command can be used to guaran-
tee sequential execution of commands and queries. When used in a command string involving a
setpoint change and if MEAS:MODE SYNC is set prior to the setpoint change, *WAI ensures the set-
point data is valid before allowing the next command in the string to be executed.
