*SAV
Meaning and Type
Save Device State
Description
This command stores the present state of the power module to a specified location in memory. Up to 10 states can be
stored. Storage locations 0 through 4 are in nonvolatile memory and locations 5 through 9 are in volatile memory. If a
particular state is desired at power on, it should be stored in location 0. It then will be recalled at power on if the power
module configuration switch is set for this mode of operation (see the power module User’s Guide).
The following power module states are stored by *SAV:
CAL:AUTO LIST:COUN OUTP:REL[:STAT] TRIG:LINK
CURR[:LEV][:IMM] LIST:STEP OUTP:REL:POL TRIG:SOUR
CURR:MODE OUTP[:STAT] OUTP:TTLT[:STAT] VOLT[:LEV][IMM]
CURR:PROT:STAT OUTP:DFI[:STAT] OUTP:TTLT:LINK VOLT:MODE
DISP:STAT OUTP:DFI:LINK OUTP:TTLT:SOUR VOLT:PROT[:LEV]
INIT:CONT OUTP:PROT:DEL TRIG:DEL

*SRE
Meaning and Type
Service Request Enable Device Interface
Description
This command sets the condition of the Service Request Enable register. This register determines which bits from the
Status Byte register (see *STB for its bit configuration) are allowed 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 and all such enabled bits then are logically ORed to cause Bit 6 of the Status Byte register to be set.
See "Chapter 4 - Status Reporting" for more details concerning this process.
When the controller conducts a serial poll in response to SRQ, the RQS bit is cleared, but the MSS bit is not. When *SRE
is cleared (by programming it with 0), the power module cannot generate an SRQ to the controller.
