Equalizer and PLL Dialog

Field Description

Track Clock

Check this checkbox to enable tracking.

Filter Cutoff and Boost

An equalizer filter is applied prior to the measurements. You can

adjust the cutoff frequency and boost of the filter.

Slicer Bandwidth

The data passes through a slicer to level the data (removes the

threshold due to low frequency effects). You can set the

bandwidth of the slicer.

PLL Bandwidth

If you checked the Clock From Data checkbox, a PLL is used to

recover the clock from the data waveform. In that case, the

bandwidth of the PLL can be adjusted.

Auto When Auto is selected, the startup frequency will be

determined by analyzing the peaks of the input signal.

PLL Startup Period From

User When User is selected, you can set the startup

frequency yourself. This is useful when the startup

frequency cannot be reliably determined from the input

signal.
