Known Pattern with Bit Clock and Marker
This tool can
operate either with the Clock Recovery option installed or with an external bit clock applied
to another input. A pattern marker is necessary and is possibly derived from the data pattern generator.
But, in many cases, this signal is not externally available and it is useful to have the SIA-3000 Pattern
Marker (PM50) option. The pattern requirements are such that it needs to be a repeating pattern.

Known Pattern w/ Bit Clock and Marker Setup Directions
This tool can

to another input. A pattern marker is necessary and is possibly derived from the data pattern generator.
But, in many cases, this signal is not externally available and it is useful to have the SIA-3000 Pattern
Marker (PM50) option. The pattern requirements are such that it needs to be a repeating pattern.
If you have the Clock recovery option installed, connect the SIA-3000 as shown below. The Data pattern
is connected to the input of the Clock Recovery input. The Clock Recovery Data output is looped back to
IN1 with the PM50 option.
From the Main Menu, press "Data" and Known Pattern with Bit Clock and Marker to open the tool.
From the main menu, you can choose if you would like to identify periodic jitter frequencies in an FFT plot.
