:MEASure Commands 24

Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 615

:MEASure:SOURce

(see page 1610)

Command Syntax

:MEASure:SOURce <source1>[,<source2>]

<source1>,<source2> ::= {<digital channels> | CHANnel<n> | FUNCtion<m>

| MATH<m> | WMEMory<r>}

<digital channels> ::= DIGital<d> for the MSO models

<n> ::= 1 to (# of analog channels) in NR1 format

<m> ::= 1 to (# math functions) 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<m>, or MATH<m> will also set :MARKer:X1Y1source to

source1 and :MARKer:X2Y2source to source2.

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 applies only to :MEASure:DELay and

:MEASure:PHASe measurements.

Return Format

| WMEM<r> | NONE}

• ":MARKer:MODE" on page 531

NOTE

MATH<m> is an alias for FUNCtion<m>. The query will return FUNC<m> if the source is

FUNCtion<m> or MATH<m>.

NOTE

FUNCtion or MATH (without the "<m>" math function number) is an alias for FUNCtion2 or

MATH2. The query will return FUNC2 if the source is FUNCtion or MATH.
