3.22 :SYSTem subsystem
The SYSTem subsystem contains miscellaneous commands that are summarized in Table 3-13.
3.22.1
:PRESet
:SYSTem:PRESet
Return to :SYSTem:PRESet defaults
Description
This command returns the instrument to states optimized for front panel operation. :SYS-
Tem:PRESet defaults are listed in the SCPI tables (Tables 3-4 through 3-16).
3.22.2
: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
Query
:POSetup?
Query power-on setup
Description
This command is used to select the power-on defaults. With RST selected, the instrument pow-
ers up to the *RST default conditions. With PRES selected, the instrument powers up to the
:SYStem:PRESet default conditions. Default conditions are listed in the SCPI tables (Tables 3-
4 through 3-16).
With one of the SAV parameters selected, the instrument powers-on to the setup that is saved in
the specified memory location using the *SAV command.
3.22.3
:VERSion?
:SYSTem:VERSion?
Read SCPI version
Description
This query command is used to read the version of the SCPI standard being used by the Model
6517A. Example code:
1991.0
The above response message indicates the version of the SCPI standard.
3.22.4
:ERRor?
:SYSTem:ERRor?
Read Error Queue
Description
As error and status messages occur, they are placed into the Error Queue. This query command
is used to read those messages. The Error Queue is a first-in, first-out (FIFO) register that can
hold up to 10 messages. Every time you read the queue, the "oldest" message is read and that
message is then removed from the queue.
If the queue becomes full, the message "350, 'Queue Overflow'" occupies the last memory loca-
tion in the register. On power-up, the queue is empty. When the Error Queue is empty, the mes-
sage "0, 'No error'" is placed in the Error Queue.
