Remote Programming
The P400 can be used as a stand-alone instrument or may be connected to a host
computer. The P400 supports serial commands for almost every action that can be
performed using the front panel.
All commands support both the SCPI long-form and the short-form mnemonic and
are not case sensitive; for example, “TRIGGER” or “trig” may be used to specify the
trigger command. Colons separate each command and instruct the unit's command
parser to move down a level in the command tree hierarchy. In situations where two
commands are issued without changing levels, a semicolon separates the
commands. The colon preceding the first command in a SCPI message instructs the
parser in the instrument to reset itself to the root level in the hierarchy. Commas
separate parameters such as numeric, extended numeric, discrete and Boolean.
Unless specifically noted, all commands have a query form, usually the command
followed by a question mark.

P400 Commands
The P400 uses mandatory remote control commands defined in the IEEE488.2-1987
standard. This command set consists of program commands and status queries that
are common to all devices. Currently these commands only clear the remote debug
buffer.
