Argument
Description
ID?
< s trin g > Query only. Returns: ID <string>; where <string> is
TEK/2230, V81.1, VERSrxx. “xx" is the firmware revision
number of the instrument.
HELp?
< s trin g > Query only. Returns a list of all valid command headers
available in the instrument.
INIt
Command only. Causes the instrument to go to an initialized
state equivalent to power-on.
LONg
[ON]
OFF
When LONg is ON, all queries respond with the full length
versions of commands. When LONg is OFF, the shortest
acceptable version of commands are used in query responses.
Default argument is ON. At power-up, LONg is OFF.
SET?
< string >
Query only. Returns an ASCII string that reflects the current
instrument state. The returned string can be sent to the
instrument to recreate that state. In order to comply with
Codes and Formats, SET? does not respond with its header.
NOTE:
This query has very limited capability because only settable
values are returned in response to the SET? query. The status
of LONg affects the length of the response to the SET? query.
