*IDN?
Read the power supply’s identification string. The power supply returns four
fields separated by commas. The first field is the manufacturer’s name, the
second field is the model number, the third field is not used (always “0”), and
the fourth field is a revision code which contains three numbers. The first
number is the firmware revision number for the main power supply processor;
the second is for the input/output processor; and the third is for the
front-panel processor.
The command returns a string with the following format (be sure to dimension
a string variable with at least 40 characters):
*TST?
Performs a complete self-test of the power supply. Returns “0” if the self-test
passes or “1” or any non-zero value if it fails. If the self-test fails, an error
message is also generated with additional information on why the test failed.
*RST
Reset the power supply to its power- on state. Table 3-3 shows the state of the
power supply after a RESET from the Recall menu or *RST command from the
remote interface.
