28 :WAVeform Commands

:WAVeform:SOURce

(see page 798)

Command Syntax

:WAVeform:SOURce <source>

<source> ::= {CHANnel<n> | FUNCtion | MATH | FFT | WMEMory<r> | SBUS1

| ABUS}

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

<r> ::= {1 | 2}

The :WAVeform:SOURce command selects the analog channel, function, or

reference waveform to be used as the source for the :WAVeform commands.

Function capabilities include add, subtract, multiply, and FFT (Fast Fourier

Transform) operations.

Query Syntax

:WAVeform:SOURce?

The :WAVeform:SOURce? query returns the currently selected source for the

WAVeform commands.

Return Format

<source> ::= {CHAN<n> | FUNC | FFT | WMEM<r> | SBUS1 | ABUS}

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

<r> ::= {1 | 2}

Example Code

' WAVEFORM_DATA - To obtain waveform data, you must specify the

' WAVEFORM parameters for the waveform data prior to sending the

' ":WAVEFORM:DATA?" query. Once these parameters have been sent,

' the waveform data and the preamble can be read.

' WAVE_SOURCE - Selects the channel to be used as the source for

' the waveform commands.

myScope.WriteString ":WAVEFORM:SOURCE CHAN1"

NOTE

MATH is an alias for FUNCtion. The :WAVeform:SOURce? Query returns FUNC if the source is

FUNCtion or MATH.
