Show Interactive Level Markers

The Show Interactive control appears at the bottom of the Configure Measurements dialog box's Thresholds tab no matter which subtab is selected. It is for displaying level markers that can be dragged up or down to make adjustments. The Show Interactive control provides these options:

• Off — Interactive level markers are not displayed.

• General Markers — For General measurements, when the Absolute or ± Hysteresis threshold methods are selected, markers that show the threshold levels are displayed. Upper threshold, middle threshold, and lower threshold markers appear for the Absolute threshold method. A single center threshold marker appears for the ± Hysteresis threshold method.

  For PAM3 General and PAM4 General measurements, when the ± Hysteresis threshold method is selected, markers that show the PAM threshold levels are displayed.

  Also for PAM3 General and PAM4 General measurements, when the Absolute level method is selected, markers that show the PAM levels are displayed.

• Rise/Fall Markers — For Rise/Fall time measurements, when the Absolute threshold method is selected, markers that show the upper and lower threshold levels are displayed.

  For PAM3 Rise/Fall or PAM4 Rise/Fall time measurements, when the Absolute level method is selected, markers that show the PAM levels are displayed.
