Theory of Operation

Waveform Edit To edit waveforms, the AWG710 Arbitrary Waveform Generator provides you with Waveform, Pattern, Sequence, Equation, and Text Editors. See Table 3±2 for a description of those editors.

Waveform Editor

The Waveform Editor lets you create or edit a waveform that is displayed on

 

the screen. It enables you to create any waveform by an operation such as

 

cut and paste, partial inversion about the horizontal or vertical axis, shift, or

 

scaling. This operation can be based on a standard waveform, such as a

 

sine or rectangular wave, or the previously created waveform.

 

The Waveform Editor also has a unique feature that edits a waveform with

 

waveform calculation functions ￿absolute value of waveform, differentiation/

 

integration, convolution, correlation, addition/subtraction/multiplication

 

between waveforms and so on￿.

 

 

Pattern Editor

The Pattern Editor displays a digital signal pattern with a pattern data placed

 

in 8/bit creation waveform memory; it creates a digital signal pattern

 

according to the High/Low settings you made for the individual bits.

 

In addition to the functions supported by the Waveform Editor, the Pattern

 

Editor is capable of generating frequently used digital signals unique to

 

digital signals and pseudo random patterns.

 

 

Sequence Editor

The Sequence Editor lets you create a more complex waveform by

 

combining different types of waveform data that you created using the

 

Waveform and/or Pattern Editors. This editor also enables a Waveform

 

listing jump and output stop to take place. They follow the external event

 

information from the EVENT IN connector as well as the number of

 

repetitions and the order for the individual pieces of waveform data.

 

 

Text Editor

The Text Editor creates an equation, more exactly, a waveform by a method

 

of equations. When an equation is created using this editor, you must

 

perform a compile.

 

The Text Editor allows you to edit plain ASCII files. It should be used to edit

 

ASCII format waveform data originated from other equipment as well as this

 

instrument itself.

 

 

Quick Edit The Quick Editor lets you modify and/or output any part of a waveform you are currently editing with the Waveform Editor. This is done in real time. The data between cursors can be scaled or shifted vertically and/or horizontally (using Expand/Shift).
