Error Detector

Data Pattern:

The Error Detector (ED) has a built in CDR for automatic clock recovery, and phase alignment. The ED also performs automatic polarity correction when required. Additionally it can detect the incoming PRBS. The input for the Data Pattern has two options, SMA [Electrical], and SFP [Optical]. SMA [Electrical] is the default input for the Error Detector.

Automatic	Error Detector determines the incoming data stream
	automatically. The supported data streams are:
	PRBS 2^7-1
	PRBS 2^15-1
	PRBS 2^23-1
	PRBS 2^31-1
SFP (Optical	The data pattern is taken from the current setting on the SFP
Generator)	generator output.
SMA (Electrical	The data pattern is taken from the current setting on the SMA
Generator)	generator output.
PRBS 2^7-1	A PRBS 2^7-1 is used for pattern synchronization.
PRBS 2^15-1	A PRBS 2^15-1 is used for pattern synchronization.
PRBS 2^23-1	A PRBS 2^23-1 is used for pattern synchronization.
PRBS 2^31-1	A PRBS 2^31-1 is used for pattern synchronization.

Input:

There are two inputs to the Error Detector, the SMA (Electrical), and the SFP (Optical).

Advanced

In the Advanced tab you can separately set the Data Patterns, and Error insertion for the SFP and SMA generator outputs.

Generator

SFP Data Pattern:

In this drop down list you have the same set of patterns, as in the setup page, to select from. The selected pattern will affect the SFP output.

SMA Data Pattern:

In this drop down list you have the same set of patterns to select from. The selected pattern will affect the SMA output.
