1 Settings HF1, HF2, HF3, LF are for transmit observation only and are not
used in the receiver data detection circuitry.
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.
■ Insert Error —Inserts 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 and Inserted errors counters to zeros.
Loopback
■ 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.
■ Stop —This control terminates the loopback tests.
■ Tx (MBps) and Rx (MBps)—Show the number of bytes of data analyzed per
second.
