1 Settings HF1, HF2, HF3, LF are for transmit observation only and are not
used in the receiver data detection circuitry.
Error Control
The Error control control displays data errors detected during analysis and allows
you to insert errors:
Detected errors—Displays the number of data errors detected in the hardware.
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.
Start
The Start control initiates transaction performance analysis.
Stop
The Stop control terminates transaction performance analysis.
Loopback
These controls display current transaction performance analysis information collected
since you last clicked Start:
TX and RX performance bars—Show the percentage of maximum theoretical data
rate that the requested transactions are able to achieve.
Tx (MBps) and Rx (MBps)—Show the number of bytes of data analyzed per
second.
