:MEASure Commands 22

Keysight InfiniiVision 3000T X-Series Oscilloscopes Programmer's Guide 499

:MEASure:SOURce

(see page 1276)

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

| EXT | NONE}

NOTE

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