*SAV <0-9>
Save State Saves the present state of the instrument to one of ten non-volatile memory locations.
Any state previously stored in the same location will be overwritten. Refer to Reset State for a list of
instrument settings that can be saved. Settings
Parameter Typical Return
0 - 9 (none)
Save state to location 1: *SAV 1
l If a particular state is desired at power-on, it should be stored in location 0. Location 0 is auto-
matically 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 is not affected by the *SAV command.
l A reset (*RST) command does not affect the instrument states stored in memory. Once a state is
stored, it remains until it is overwritten or specifically deleted.
*SRE <value>
*SRE?
Service Request Enable Command and Query. Sets the value of the Service Request Enable register.
This determines which bits from the Status Byte Register are summed to set the Master Status
Summary (MSS) bit and the Request for Service (RQS) summary bit. A 1 in any Service Request Enable
register bit position enables the corresponding Status Byte register bit. All such enabled bits are then
logically OR-ed to cause the MSS bit of the Status Byte register to be set. Refer to Status Tutorial for
more information.
The query reads the enable register and returns a decimal value which corresponds to the binary-
weighted sum of all bits set in the register.
Parameter Typical Return
A decimal value that corresponds to the binary-weighted sum of the bits
in the register.
<bit value>
Enable bit 3 and 4 in the enable register: *SRE 24
l When a serial poll is conducted in response to a service request, RQS is cleared but MSS is not.
l When *SRE is cleared (by programming it with 0), the power analyzer cannot generate a service
request.
*STB?
Status Byte Query. Reads the Status Byte Register, which contains the status summary bits and the
Output Queue MAV bit. The Status Byte is a read-only register and the bits are NOT cleared when it is
read. Refer to Status Tutorial for more information.
