Time at Max

Time at Max is the time of the first occurrence of the absolute maximum waveform level on the waveform.

The measurement can be restricted to a region. Time at Max is position independent. Therefore, the instrument uses the entire waveform on the display graticule to determine the maximum signal level. An annotation label is placed at the result.

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 button.
  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.
