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