:MEASure Commands 20
Agilent InfiniiVision 2000 X-Series Oscilloscopes Programmer's Guide 361
:MEASure:SOURce
(see page 790)
Command Syntax
:MEASure:SOURce <source1>[,<source2>]
<source1>,<source2> ::= {<digital channels> | CHANnel<n> | FUNCtion
| MATH | WMEMory<r> | EXTernal}
<digital channels> ::= DIGital<d> for the MSO models
<n> ::= 1 to (# of analog channels) in NR1 format
<r> ::= 1-2 in NR1 format
<d> ::= 0 to (# digital channels - 1) in NR1 format
The :MEASure:SOURce command sets the default sources for
measurements. The specified sources are used as the sources for the
MEASure subsystem commands if the sources are not explicitly set with
the command.
If a source is specified for any measurement, the current source is
changed to this new value.
If :MARKer:MODE is set to OFF or MANual, setting :MEASure:SOURce to
CHANnel<n>, FUNCtion, or MATH will also set :MARKer:X1Y1source to
source1 and :MARKer:X2Y2source to source2.
EXTernal is only a valid source for the counter measurement (and
<source1>).
Query Syntax
:MEASure:SOURce?
The :MEASure:SOURce? query returns the current source selections. If
source2 is not specified, the query returns "NONE" for source2. If all
channels are off, the query returns "NONE,NONE". Source2 only applies to
:MEASure:DELay and :MEASure:PHASe measurements.
Return Format
<source1>,<source2><NL>
<source1>,<source2> ::= {<digital channels> | CHAN<n> | FUNC | WMWM<r>
| EXT | NONE}

NOTE
MATH is an alias for FUNCtion. The query will return FUNC if the source is FUNCtion or
MATH.
