20 :FUNCtion<m> Commands

:FUNCtion<m>:SOURce2

(see page 1610)

Command Syntax

:FUNCtion<m>:SOURce2 <value>

<m> ::= 1 to (# math functions) in NR1 format

<value> ::= {CHANnel<n> | WMEMory<r> | NONE}

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

<r> ::= 1 to (# ref waveforms) in NR1 format

The :FUNCtion<m>:SOURce2 command specifies the second source for math

operator functions that have two sources. (The :FUNCtion<m>:SOURce1

command specifies the first source.)

The :FUNCtion<m>:SOURce2 setting is not used for the transform functions, filter

functions, or visualization functions (except when the measurement trend

visualization's measurement requires two sources).

When :FUNCtion<m>:OPERation is TRENd, the :FUNCtion<m>:SOURce2

command reports error -221,"Settings conflict" because the TRENd function

operates on a measurement and not a source waveform.

Query Syntax

:FUNCtion<m>:SOURce2?

The :FUNCtion<m>:SOURce2? query returns the currently specified second source

for math operations.

When :FUNCtion<m>:OPERation is TRENd, the :FUNCtion<m>:SOURce2? query

returns the source of the measurement.

Return Format

<value> ::= {CHAN<n> | WMEM<r> | NONE}
