* PSC 0 | 1
POWER ON STATUS CLEAR determines whether the contents of the ENABle registers are
preserved or reset during power-up.
*PSC = 0 causes the contents of the status registers to be preserved. Thus a service request can be
generated when switching on the instrument, if the status registers ESE and SRE are suitably
configured.
*PSC
=
0 'Resets the registers.
The query form *PSC? reads out the contents of the power-on-status-clear flag. The response can be 0 or 1.
*RST
RESET sets the instrument to a defined default status. The command essentially corresponds to
pressing the PRESET key. The default setting is indicated in the description of the commands.
*SRE 0 to 255
SERVICE REQUEST ENABLE sets the service request enable register to the indicated value. Bit 6
(MSS mask bit) remains 0. This command determines under which conditions a service request is
generated. The query form *SRE? reads the contents of the service request enable register in
decimal form. Bit 6 is always 0.
*STB?
READ STATUS BYTE QUERY reads out the contents of the status byte in decimal form.
*TRG
TRIGGER initiates all actions in the currently active test screen expecting a trigger event. This
command corresponds to
INITiate:IMMediate
(cf. Section "TRIGger Subsystem").
*TST?
SELF TEST QUERY initiates the selftest of the instrument and outputs an error code in decimal form
(0 = no error).
*WAI
WAIT-to-CONTINUE permits servicing of subsequent commands only after all preceding commands
have been executed and all signals have settled (cf. Chapter 5 and "*OPC" as well).
