Query Syntax

:WAVeform:SOURce?

Description

Selects the source waveform from which to return the waveform data points. The following two non-standard waveform arguments are available when an N1000A-PTB, 86100D-PTB, 86108B-PTB module, or 86107A precision timebase is used:

FIPHase0
Selects the In Phase Waveform that is shown on the Precision Timebase tab of the Setup dialog.
FQUadrature0
Selects the Quadrature Waveform.

Use the queries shown in the following table to actually return the data. These queries return data in different formats requiring scaling of the data.
