Agilent InfiniiVision 5000 Series Oscilloscopes Programmer's Guide 521

:WAVeform:SOURce

(see page 658)

Command Syntax

:WAVeform:SOURce <source>

<source> ::= {CHANnel<n> | FUNCtion | MATH | SBUS}

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

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

serial decode bus to be used as the source for the :WAVeform commands.

Function capabilities include add, subtract, multiply; integrate,

differentiate, and FFT (Fast Fourier Transform) operations.

When the :WAVeform:SOURce is the serial decode bus (SBUS), ASCii is the

only waveform format allowed.

Query Syntax

:WAVeform:SOURce?

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

the WAVeform commands.

Return Format

<source> ::= {CHAN<n> | FUNC | SBUS}

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

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.
