GPIB Commands
B (No Query Form)
Syntax
Example:
*CLS (No Query Form)
2706 RF Preselector
This section contains an alphabetical listing of the common commands (preceded
by an asterisk) and device commands used to operate the Preselector from a
remote GPIB controller. The listing explains the function and syntax of each
command and gives examples of its use.
Most of these commands can be used either as set commands or queries.
However, some commands can only be used to set: these have the words "No
Query Form" included with the command name. Other commands can only be
used to query: these have a question mark appended to the header, and include
the words "Query Only" in the command name.
The B (Band) command selects the RF filter of the Preselector.
