Controlling the Instrument and Acquiring Data with Commands
Command Format
(1) Command Format
The ST5520 commands have the following structure.
Command (+Parameter) + Delimiter
The command and the parameter are separated by “ “ ( one character space )
If there is no parameter, send the delimiter after the command.
The command may consist of both upper and lower case
letters. Make sure to use
one character space as the separator between the command and the parameter.
1.
When the command contains a parameter
:VOLTage 100
(+delimiter)
the command format consists of the command :VOLTage
followed by the separator “ “( one character space ). Then follows the parameter
100 . Following the parameter comes the delimiter
2. When the command contains no parameter
:STOP
(+delimiter)
the command format consists of the command :STOP immediately followed by the
delimiter.
The meaning of the delimiter is to separate commands and data. When the ST5520
receives the delimiter, it starts analysis of the command.
A command can abbreviated. The whole command form is referred to as the “long
form” and the abbreviated form as the “short form.”
Although the short form is printed in upper case letters and the rest in lower case
letters in this instruction manual,sending command (including parameter and
delimiter) from personal computer in either upper or lower case letters is valid.
All responses returned from the ST5520 are in upper case letters.

VOLT

VOLTA,VOL
