The Eye mode PAM Pmin measures the minimum power on the eye diagram. The Pmin measurement is not affected by the settings in the Configure Measurements dialog. Pmin is based on a 1e-2 hit ratio, where Pmin is the largest power level that results in the number of samples below that level not exceeding the product of hit ratio and total number of observed samples. All samples are acquired in a single unit interval eye diagram.

When the measurement is selected, the Select Measurement Settings dialog opens where you can specify Hit Ratio and Units (Watts or dBm). By default, the Hit Ratio is set to1.0E-2.

This measurement is not affected by the settings in thePAM-N Analysis Setup dialog.

This measurement can also be performed on an NRZ signal.

To measure

  1. Select Eye/Mask Mode.
  2. Click Auto Scale in the menu toolbar.
  3. Click the toolbar's PAM tab.
  4. On the toolbar, locate and click the Pmin button.
