Remote Operation Commands

The Instrument accepts commands for setting parameters, executing functions or
responding with requested data. These commands are in the form of strings of ASCII-
encoded characters.
Commands consist of a command header and, if necessary, parameter data. All
commands must be terminated with either a carriage return (ASCII 0D hex or 13
decimal) or new line character (ASCII 0A hex or 10 decimal).
Command headers consist of one or more mnemonics separated by colons (:).
Mnemonics may use letter characters, the underscore character (_), and possibly numeric
digits as well. Commands are not case sensitive. Mnemonics often have alternate forms.
Most mnemonics have a long form that is more readable and a short form consisting of
three or four characters that is more efficient.
Query commands are commands that request data in response. Query commands have a
question mark (?) immediately following the command header. Responses to query
commands are generated immediately and placed in the output buffer. Responses are then
transmitted automatically to the PC.
Some commands require parameter data to specify values for one or more parameters.
The command header is separated from the parameter data by a space (ASCII 20 hex or
32 decimal). Multiple parameters are separated by a comma(,).
