Measurements

You can perform up to 64 simultaneous measurements on displayed waveforms.

To add measurements, see:

• Add Measurements Dialog Box
• Left-Side Bar and Drag-and-Drop Measurements

Once added, measurement results are displayed in the Results panel:

• Measurement Results

Measurements can be selected from the following categories:

• Time Measurements — Horizontal measurements on time domain waveforms.
• Amplitude Measurements — Vertical measurements on waveforms.
• Clock Measurements — Measurements on clock waveforms.
• Data Measurements — Measurements on data waveforms.
• Eye Measurements — Special measurements for NRZ (Non-Return-to-Zero) eye diagrams. NRZ signals use two vertical levels to transfer information, and eye diagrams show one eye.
• PAM Measurements — Special measurements for PAM (Pulse Amplitude Modulation) waveforms. PAM signals use three, four, or more vertical levels to transfer information. See also PAM-N Analysis Setup Dialog Box.
• FFT Measurements — Measurements on FFT math function waveforms.
• User-Defined Measurements — These are custom scalar measurements that you create using Python, MATLAB, or Compiled MATLAB. User-defined measurements can be defined for waveforms or real-time eye diagrams (pixel-hit databases).
