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.
