Data Type
The Data Type control specifies the type of data pattern contained in the transactions.
Select the following available data types for analysis:
• PRBS: pseudo-random 7-bit sequences (default)
• PRBS15: pseudo-random 15-bit sequences
• PRBS23: pseudo-random 23-bit sequences
• PRBS31: pseudo-random 31-bit sequences
•
HF: highest frequency divide-by-2 data pattern
• LF: lowest frequency divide by 33 data pattern
Settings Hf and LF are for transmit observation only and are not intended for use in
the receiver data detection circuits.
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 Errrors: Displays the number of errors inserted into the transmit data
stream.
• Insert Error: 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 are able to achieve.
Start: This control initiates the loopback tests.
