4.22.2 :POSetup <name>
:SYSTem:POSetup <name> Program power-on defaults
Parameters <name> = RST Select *RST defaults on power up
= PRESet Select :SYSTem:PRESet defaults on power up
= SAVX Select saved defaults on power up
where; X = 0 to 9
Format :syst:pos <name>
Query :POSetup? Query power-on setup
Short-form format: :syst:pos?
Response message: RST, PRES, SAV0-SAV9
Description This command is used to program the power-on defaults. With RST selected, the instrument will
power up to the *RST default conditions. With PRES selected, the instrument will power up to
the :SYStem:PRESet default conditions. Appendix B defines the default conditions for these
commands.
With one of the SAV parameters selected, the instrument will power-on to the setup that is saved
in the specified memory location using the *SAV command. Valid SAV parameters depend on
which memory option is installed in the Model 2001 and are summarized as follows:
Memory option Valid SAV parameters
STD SAV0
MEM1 SAV0 through SAV4
MEM2 SAV0 through SAV9
Programming example 10 OUTPUT 716; “:syst:pos pres; pos?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Two commands in this program message; the first selects :SYSTem:PRESet power-on
defaults, and the second queries the power-on setup.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the power-on setup (PRES).
4.22.3 :FRSWitch?
:SYSTem:FRSWitch? Read INPUTS switch
Format :syst:frsw?
Description This query command is used to read the position of the FRONT/REAR INPUTS switch. After
sending this command and addressing the Model 2001 to talk, the code that indicates switch po-
sition will be sent to the computer. Switch position code is defined as follows:
1 = Front panel inputs selected
0 = Rear panel inputs selected
