16 Keysight U2741A Programmer’s Reference Guide
The SCPI language defines several different data formats to be used in program
messages and response messages.
Numeric Commands that require parameters to accept all commonly used decimal
representations of numbers including optional signs, decimal points, and
scientific notation. You can also send engineering unit suffixes with
numeric parameters, for example, M Ω or k Ω .
Discrete Parameters used to program settings that have a limited number of
values, for example,
BUS
,
IMMediate
,
EXTernal
. They have a short form
and a long form just like command keywords. You can mix upper- and
lower-case letters. Query responses will always return the short form in all
upper-case letters.
Boolean Parameters that represent a single binary condition that is either true or
false. For a false condition, the U2741A will accept
OFF
or
0
. For a true
condition, the U2741A will accept
ON
or
1
. When you query a boolean
setting, the U2741A will always return
0
or
1
.
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.
