Agilent Technologies 34401A - Manual (Page 151)

*ESR?
Query the Standard event register. The multimeter returns a decimal
value which corresponds to the binary-weighted sum of all bits set in the
register.
*OPC
Sets the “operation complete” bit (bit 0) in the Standard Event register
after the command is executed.
*OPC?
Returns “1” to the output buffer after the command is executed.
*PSC {0|1}
Power-on status clear. Clear the Status Byte and Standard Event
register enable masks when power is turned on (
*PSC 1 ). When *PSC 0
is in effect, the Status Byte and Standard Event register enable masks
are not cleared when power is turned on. [Stored in non-volatile memory]
*PSC?
Query the power-on status clear setting. Returns “0” ( *PSC 0 ) or
“1” ( *PSC 1 ).
*SRE < enable value >
Enable bits in the Status Byte enable register.
*SRE?
Query the Status Byte enable register. The multimeter returns a
decimal value which corresponds to the binary-weighted sum of all bits
set in the register.
*STB?
Query the Status Byte summary register. The *STB? command is
similar to a serial poll but it is processed like any other instrument
command. The
*STB? command returns the same result as a serial
poll but the “request service” bit (bit 6) is not cleared if a serial poll
has occurred.
