Reset the instrument: *RST
l *RST forces the ABORt command. This cancels any trigger actions presently in process, and resets the WTG bit in
the Status Operation Condition register.
*SAV <0-9>
Saves the present state of the instrument to one of ten non-volatile memory locations.
Parameter Typical Return
0 - 9 (none)

l If a particular state is desired at power-on, it should be stored in location 0. Location 0 is automatically recalled at
power turn-on when the Output Power-On state is set to RCL 0.
l The calibration state is NOT saved as part of the *SAV operation.
l Data saved in non-volatile memory, described in the Non-volatile Settings, is not affected by the *SAV command.
l When shipped, locations 0 through 9 are empty.
*TST?
Self-Test Query. Performs a instrument self-test. If test fails, one or more error messages will provide additional inform-
ation. Use SYSTem:ERRor? to read error queue. See SCPI Error Messages for more information.
Parameter Typical Return

Perform self-test: *TST?
l The power-on self-test is the same self-test performed by *TST.
