Introduction to SCPI 1
U2761A Programmer’s Reference 9
String
Parameters that contain virtually any set of ASCII characters. A string
must begin and end with matching quotes; either with a single quote or a
double quote. You can include the quote delimiter as part of the string by
typing it twice without any characters in between. The following command
uses a string parameter:
CALibration:STRing <quoted string>
Address list
An address list must be preceded with the “@” symbol and must be
enclosed in parentheses “( )”. Use the following syntax to specify the
U2761A address list:
(@<address>[,<address>])
The address list parameter allows you to specify a single address or
multiple addresses.
For example, address 1 is specified in the following command:
→ CONF:SSI SLAV, (@1)
An address list of 1 and 3 is specified in the following command:
→ CONF:SSI MAST, (@1,3)
Input message terminators
Program messages sent to a SCPI instrument must terminate with a
<newline> character. The IEEE-488 End-Of-Identify (EOI) signal is
interpreted as a <newline> character and may also be used to terminate a
message in place of the <newline> character. A <carriage return> followed
by a <newline> is also accepted. Many programming languages allow you
to specify a message terminator character or EOI state to be automatically
sent with each bus transaction. Message termination always sets the
current path back to the root level.
NOTE
The CONFigure:SSI command is the only U2761A command that uses the address list
parameter.
