*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

*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.
