NOTE
The following commands take a long time to process and may benefit from
using *OPC or *OPC?:
using *OPC or *OPC?:
•
*RST and SYST:PRES
•
*RCL and *SAV
•
ROUT:MULT:CLOS and ROUT:MULT:OPEN – Only if the <clist> is long.

CALC2:IMM and CALC2:IMM?– Only when performing the standard
deviation calculation on a large buffer. A 10,000 point buffer takes around
5.75 seconds.

5.75 seconds.
D *OPT? — option query
Query installed switching modules
Use this query command to determine which switching modules are installed in the
Model 2750. For example, if a Model 7703 is installed in slot 1, and the other slots are
empty, the response message will look like this:
Model 2750. For example, if a Model 7703 is installed in slot 1, and the other slots are
empty, the response message will look like this:
7703, NONE, NONE, NONE, NONE
Note that the model number of an installed pseudocard is returned in the same manner. See
E *SAV <NRf> — save
Save present setup in memory
*RCL <NRf> — recall
Return to setup stored in memory
Parameters
0
= Memory
location
0
1
= Memory location 1
2
= Memory location 2
Use the *SAV command to save the present instrument setup configuration in memory for
later recall. Any control affected by *RST can be saved by the *SAV command. The *RCL
command is used to restore the instrument to the saved setup configuration. Three setup
configurations can be saved and recalled. A saved setup is approximately 4k bytes in size.

Model 2750 ships from the factory with SYSTem:PRESet defaults loaded into the avail-
able setup memory. If a recall error occurs, the setup memory defaults to the
SYSTem:PRESet values.
able setup memory. If a recall error occurs, the setup memory defaults to the
SYSTem:PRESet values.
NOTE
For RS-232 operation, *OPC or *OPC? should be used with *SAV and *RCL,
which are slow responding commands. Details on *OPC and *OPC? are pro-
vided in Section 12.

vided in Section 12.
Programming example:
*SAV 2
' Save present setup in memory location 2.
*RST
' Return 2750 to RST defaults.
*RCL 2
' Return (recall) 2750 to setup stored in memo location 2.
F *RST — reset
Return Model 2750 to RST defaults
When the *RST command is sent, Model 2750 performs the following operations:
1.
Returns Model 2750 to the RST default conditions (see “Default” column of SCPI
tables).
