Common Commands
:SYSTem:ERRor?
Syntax:
:SYSTem:ERRor?
Returns the first error in the error queue. The error will be removed from the error queue.
The error message consists of an error code (integer) and an error message. When no error is in the
queue, the error code is zero and the message is “No Error”. The code and the message are
separated by a comma.
Example query:
SYST:ERR?
Example response:
0,"No Error"
:SYSTem:ERRor:COUNt?
Syntax:
:SYSTem:ERRor:COUNt?
Returns the number of errors in the error queue. The error queue will not be modified.
Example query:

0
:SYSTem:HELP:HEADers?
Syntax:
:SYSTem:HELP:HEADers?
Returns a list of all supported SCPI headers, separated by carriage-return characters (“\r”, see also
page 23).
Example query:
SYST:HELP:HEAD?
Example response:
"*IDN\r*RST\r:SYSTem:ERRor?\r:SYSTem:HELP:HEADers?"
The actual response will contain many more headers. Depending on the software that you use, the
“\r” character might be displayed as a new line or not.
:SYSTem:SELFtest?
Syntax:
:SYSTem:SELFtest?
Conducts a self-test of all testable components of the instrument. The tests are the same tests that
are conducted when the
*TST?
Query (see page 25) is issued.
In a master/slave configuration, the slave frame will also be tested.
After the self-tests are complete, which might take a while, a string is returned. If all self-tests pass,
the string is
"pass"
; otherwise, the string starts with
"fail"
, followed by a human-readable
description of the detected problems.
Note that the self-tests will take a while to complete, depending on how many and which modules
are installed. You’ll probably receive a time-out from your VISA client, unless the VISA timeout is
programmed to 30 seconds or more.
Example query:
SYST:SELFtest?
Example response:
"pass"
:SYSTem:CONFiguration?
