Status Reporting Commands
114
*ESR?
Query the Standard Event register. The power supply returns a decimal value which
corresponds to the binary-weighted sum of all bits in the register.
*OPC
Set the ‘‘Operation Complete’’ bit (bit 0) of the Standard Event register after the
command is executed.
*OPC?
Return ‘‘1’’ to the output buffer after the command is executed.
*PSC { 0 | 1 }
(Power-on status clear.) This command clears the Status Byte and the 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.
*PSC?
Query the power-on status clear setting. The returned parameter is ‘‘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 power supply returns a decimal value
which corresponds to the binary-weighted sum of all bits set in the enable 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.
*WAI
Instruct the power supply to wait for all pending operations to complete before
executing any additional commands over the interface. Used only in the triggered
mode.
