Data Type
The Data Type control specifies the type of data pattern contained in the transactions.
Select the following available data types for analysis:
• PRBS7: pseudo-random 7-bit binary sequences
• PRBS15: pseudo-random 15-bit binary sequences
• PRBS23: pseudo-random 23-bit binary sequences
• PRBS31: pseudo-random 31-bit binary sequences (default)
Error Control
This control displays data errors detected during analysis and allows you to insert
errors:
• Detected Errors: Displays the number of data errors detected in the received bit
stream.
• Inserted Errors: Displays the number of errors inserted into the transmit data
stream.
• Bit Error Rate: Calculates the bit error rate of the transmit data stream.
• Insert: Insert a one-word error into the transmit data stream each time you click
the button. Insert Error is only enabled during transaction performance analysis.
• Clear: Resets the Detected Errors counter and Inserted Errors counter to zeros.
Run Control
• TX and RX performance bars: Show the percentage of maximum theoretical
data rate that the requested transactions can achieve.
• Start: This control initiates the loopback tests.
• Data Rate: Displays the XCVR type and data rate of each channel.
