# Amplitude at Time

Amplitude at Time is the measure of the amplitude of a waveform at a specific time.

The Amplitude-at-Time measurement can be restricted to a region.

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

## Configurable Measurement Parameters

This measurement is not affected by setting in the Configure Measurements dialog box.

## To measure

1. Click the toolbar's Amplitude tab.
2. Click the toolbar's More buttons to locate the Amplitude at Time button, and click it.
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. Enter the Time at which to perform the measurement.
