Command Reference
Command Reference
*TST?
The *TST? query command performs the self-test and self-calibration, and returns
the results in ASCII format. Modules that fail the self-test are disabled, and can only
be enabled by the RCV command.
After the *TST? command, read the results soon.
Execution
Conditions
No module may be in the HIGH VOLTAGE state (forcing more than ±42 V, or
voltage compliance set to more than ±42 V).
To perform the self-test correctly, the measurement terminals should be opened.
Syntax
*TST? [ slotnum ]
Parameters
slotnum : Specifies the module to test. Integer expression. 0 to 9.
0: Mainframe and all modules. Default setting.
1 to 8: Module installed in the slot specified by slotnum .
9: Mainframe.
For HPSMU that uses two slots, set the greater slot number. For example, if it is
installed in slot 3 and 4,
slotnum must be 4.
If slotnum specifies the slot that installs no module, this command causes an error.
Query Response
results <CR/LF^EOI>
results returns the sum of the following values corresponding to the failures.
