Jitter Filter Function
The jitter filter function generates a time sequence of jitter measurements that are filtered by the
selected band-pass filter. Low-pass and high-pass frequencies are set in the function’s menu.
You must enter the bit frequency (data rate) to set the sampling rate for the digital filter. This
function is only valid when operating on the TIETrend trace generated by the SDA. The low
frequency corner is limited by the record length (longer records are required for lower cutoff
frequencies). If an invalid lower cutoff frequency is chosen, the filter reverts to low-pass.
