Time at Amplitude

Time at Amplitude is the measure of the time at which the specified edge amplitude occurs on the displayed waveform.

When this measurement is selected, a dialog box appears from which you select the edge number, direction, amplitude value, and if it is restricted to a region.

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

• Thresholds tab

To measure

1. Click the button and enter the waveform edge number, amplitude, and direction at which to perform the measurement.
2. 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.
