SCPI Signal Oriented Commands
Model 2750 Multimeter/Switch System User’s Manual
The signal oriented measurement commands are used to acquire readings. You can use
these high level instructions to control the measurement process. These commands are
summarized in
NOTE
When measurements are performed, the readings are fed to other enabled oper-
ations.
explains “
” and provides addi-
tional information on using FETCh?, READ?, and MEASure? to acquire
readings.
NOTES
The CONFigure:<function> and MEASure:<function>? commands can be sent
without any of the optional parameters (<rang>, <res>, or <clist>). For
details, see the “Description” for the CONFigure and MEASure commands.
When using the <clist> parameter, it is interpreted as the last parameter. Any
parameter after <clist> will generate error -102 (syntax error).
If only one parameter is used and it is not a <clist>, it is interpreted as the
range parameter (<rang>).
If two parameters are used and the second one is not a <clist>, the first param-
eter is the range parameter (<rang>) and the second is the resolution parameter
(<res>).
The CONFiguration and MEASure? commands for the TEMPerature and CON-
Tinuity functions do not use the <rang> and <res> parameters. The command
is ignored and causes error -108 (parameter not allowed).
The CONFigure and MEASure? commands cannot be used while scanning. The
command is ignored and causes error -221 (settings conflict).

Signal oriented measurement command summary
Command
Description
CONFigure:<function> [<rang>], [<res>], [<clist>] Places the Model 2750 in a “one-shot” measurement
mode for the specified function.
FETCh?
Requests the latest reading.
READ?
Performs an ABORt, INITiate, and a FETCh?.
MEASure[:<function>]? [<rang>], [<res>], [<clist>] Performs an ABORt, CONFigure:<function>, and a
READ?. (See Note).
Channel list parameter:
<clist> = (@SCH)
where: S
= Mainframe slot number (1, 2, 3, 4, or 5)
CH = Switching module channel number (must be 2 digits)
Examples:
(@101) = Slot 1, Channel 1
(@101, 203) = Slot 1, Channel 1 and Slot 2, Channel 3
(@101:110) = Slot 1, Channels 1 through 10
Note: Only one channel can be specified in the <clist> for the MEASure? command.
