Overview of Command
The information that is exchanged between the controller (computer) and the device (PCR-M
series) is called a message.
The PCR uses the SCPI language for the messages.
There are two types of messages, commands that are sent from the computer to the PCR
and responses that are sent from the PCR to the computer.
Command Hierarchy
SCPI commands are ASCII-based commands designed for test and measurement devices.
The command hierarchy is structured around the common root or node, which is the
construction block of the SCPI subsystem. A command consists of a program header,
parameters, and punctuation.
The hierarchy is explained using the SOURce subsystem as an example.
Program header
Parameter Hierarchy of node
SOUR:
Root node
FREQ
Second level
:LIM
Third level
:UPP
<numeric> Fourth level
:LOW <bool>
Fourth level
VOLT
Second level
:RANGE
Third level
:UPP
<numeric> Fourth level
:AUTO <bool>
Fourth level
A higher node is separated from a lower node using a colon (:).
Command Syntax
This manual denotes SCPI commands using the following format.
MEASure[:SCALar]:CURRent:DC? {<numeric>|MINimum|MAXimum}
SCPI commands can be issued using the short form. The short form of a SCPI command is
the section of the command written in uppercase.
SCPI commands can be sent in the long form or short form. Since SCPI commands are not
case-sensitive, CURR, Curr, and curr are all accepted as the short form of CURRent. In the
long form, CURRENT, Current, and current are all acceptable.
・
A space is required between the program header section and the parameter section.
・
Multiple parameters, when available, are concatenated using commas.
・
Commands are concatenated using semicolons (compound command).
TRIGger:SEQuence2:SOURce PHASe;PHASe 270
In the second command, TRIGger:SEQuence2 is omitted. This is because the path is set to
TRIGger:SEQuence2 by the first command TRIGger:SEQuence2:SOURce PHASe.
This compound command is the same as entering the following commands.
TRIGger:SEQuence2:SOURce PHASe
TRIGger:SEQuence2:PHASe 270
An error occurs if a node that is not defined in the current path is designated.
Commands of different subsystems can be concatenated using a colon and a semicolon
together.
SOURce:CURRent MINimum;:MEASure:CURRent:AC?
This compound command contains two root nodes, SOURce and MEASure.
When the second or subsequent command starts with a colon, the path specified by the
previous command is cleared.
・
The maximum number of characters that can be transmitted in a single line is 128.
