Learn about the Math Waveform controls.

Learn about the Equation Editor.

Set up math averaging

From the Math menu, select Set Math Averages.

Overview

Use this control window to specify the number of times the selected

math waveform

is averaged.

To use

1. Click in a Math <1–4> n = entry box to map it to one of the multipurpose knobs.

2. Use the multipurpose knob to specify the number of times the selected waveform should be averaged.

Behavior

The selected math waveform is averaged over the number of acquisitions shown in the control. Each math waveform has its own
set of controls.

The following buttons allow you to change other setups after you set the averaging:

■

Click Editor to open the Math Equation Editor control window.

■

Click Spectral to open the Spectral Setup control window.

■

Click Setup to open the Math Setup control window.
