# Average

Average is a measure of the mean value of the data sampled from a region or a single cycle. This measurement is compatible with electrical PAM signals over the region. It is not compatible over a single cycle.

The record length of the waveform determines the number of data samples used for the measurement. The measurement can be restricted to a region. Annotation labels are placed on the waveform to mark the average value. Average is most suitable for single-valued waveforms.

This command is PAM compatible when it is made over the display or a region. It is not PAM compatible when made over a cycle.

The measurement can be performed on any waveform that is displayed in one of a Waveform content windows.

## Configurable Measurement Parameters

This measurement is affected by the following settings (choose Measure > Thresholds...):

- Thresholds tab

## To measure

1. Click the toolbar's More buttons to locate the Average button.
2. Click the button.
3. Select the Region in which to make the measurement:
   - Displayed Waveform — is what you see in the waveform window (which can be a zoomed-in view of the complete waveform).
   - Entire Waveform — specifies the complete waveform.
   - Region N — If regions are enabled for the selected signal, you can select one of those regions.
4. Select the Measurement Area (Single Cycle or Entire Region).
5. When measuring a single cycle, select the Edge Direction that identifies the cycle to measure:
   - Rising or Falling — the cycle beginning with this edge that is nearest to the timebase reference is the cycle to measure.
