5.3 Remote Communication
Device control, results readout and measured values collection remotely is performed using device
commands compatible with SCPI standard (Standard Commands for Programmable Instruments).
Main rules of SCPI standard:
•
parentheses { } restrict parameter in the command strain
•
parentheses [ ] restrict optional parameters or parts of commands
•
parentheses < > restrict parameter, which is due to be replaced by the value
•
perpendicular line ( | ) separate options, from which exactly one has to be chosen
•
character case in the command is optional (command SYST:VERS? is identical with sYsT:VeRs?)
You can use the USB interface as well as the RS232 interface to send the commands. Each command
must be ended with <CR><LF> resp. <EOL> (\r\n) signs (e.g.
*IDN?
<CR><LF> ), otherwise the device
does not respond! The default port setting values are following: BaudRate
– 57600, DataBit – 8, Parity
– None, StopBit – 1. For sending the SCPI commands you can use the AP Terminal utility, which you
can find in the Servicer subdirectory of your WS installation.(called Terminal.exe), see figure below.
