## Command Syntax

    :MEASure:USER:USER{1:8}:SOURce{1:2} {CHANnel{N} | DIFF{1:8}{A|C} | FUNCtion{1:64} | WMEMory{1:8}}

{N} identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is CHANnel4_2.

## Description

Selects the source waveforms on which to perform the USER measurement. If one source waveform is required, use `:SOURce` or `:SOURce1`. If two source waveforms are required, use `:SOURce2`. If an XML file was used to define the test, the test source waveforms are specified in the file's XML <SourceIndex> tag in combination with the Select Source dialog box when the measurement is started.

Use the `:MEASure:USER:USER{N}` parent command to turn on the measurement and return the measured value.
