The *SAV command is used to save the current instrument setup configuration in memory for
later recall. Any control affected by *RST (see
mand. The *RCL command is used to restore the instrument to a saved setup configuration (see
paragraph 4.10.9).
If the Model 2001 does not have any extended memory installed, only one setup configuration
can be saved and recalled. In this situation, memory location "0" is the only valid parameter for
the *SAV command. If the Model 2001 has the Model 2001-MEM1 memory element installed,
up to five setup configurations can be saved and recalled. In this situation, memory locations "0"
through "4" are valid parameters. If the Model 2001 has the Model 2001-MEM2 memory ele-
ment installed, up to 10 setup configurations can be saved and recalled. Memory locations "0"
through "9" are then valid parameters.

The *SRE command is used to set the contents of the Service Request Enable Register. This
command is sent with the decimal equivalent of the binary value that determines the desired
state (0 or 1) of each bit in the register.
This enable register is used along with the Status Byte Register to generate service requests
(SRQ). With a bit in the Service Request Enable Register set, an SRQ will occur when the cor-
responding bit in the Status Byte Register is set by an appropriate event. For details on register
structure, refer to paragraph
