Query Syntax *STB?
Returned Parameters (Register binary value)
Related Commands *SRE *ESE *ESR
5.12 *TRG
This command generates a trigger to any subsystem that has BUS selected as its source (for
example, TRIG:SOUR BUS).The command has the same affect as the Group Execute Trigger
() command.
Command Syntax *TRG
Parameters None
Related Commands ABOR INIT TRIG[:IMM]
5.13 *TST?
This query causes the AC Source to do a self-test and report any errors. The selftest will run until
the first error is encountered and terminate. The response to the query will either be the first error
encountered or 0 is no error was found. (Selftest passed). For a list of error messages, refer to
Appendix C.
Note: The selftest should always be run in 3 phase mode on all Lx models and Ls models with the
–MODE option. If the selftest is run in single phase mode, not all aspects of the Phase 2/B and
3/C hardware will be tested as a result. If the power source is a Ls-1 single phase only
configuration, the selftest can only be run in single phase mode.
Note: The following settings must be in effect before sending the *TST? Command:
OUTP 0 Output relay must be open
INST:NSEL ALL;:FUNC SIN On all Lx models and Ls models with the –ADV option, it is
required to set the waveform for all three phases to SIN
(sinewave).
VOLT:RANG MIN The LOW voltage range (135, 156 or 200) must be selected.
VOLT:ALC ON The ALC mode must be set to ON.
Note: The selftest is always performed at 400 Hz, 115 Vac. This is required to obtain the correct
internal test current based on the buit-in selftest loads. However, the output relay is open during
the selftest and no output is present on the output terminals during the selftest. At the end of the
selftest, the output relay remains open and the voltage is set to 0V. The frequence remains set to
400 Hz on Ls/Lx models with firmware revisions 0.97 or lower. On Lx/Ls models with firmware
revision 0.98 or higher, the programmed frequency will return to the value set before execution of
the selftest command.
