PMA Setting
Allows you to make changes to the PMA parameters that affect the active transceiver
interface. The following settings are available for analysis:
•
Serial Loopback: Displays the signal status between the transmitter and the
receiver.
•
VOD: Specifies the voltage output differential of the transmitter buffer.
•
Pre-emphasis tap:
— Pre-tap 1: Specifies the amount of pre-emphasis on the first pre-tap of the
transmitter buffer.
— Pre-tap 2: Specifies the amount of pre-emphasis on the second pre-tap of the
transmitter buffer.
— Post-tap 1: Specifies the amount of pre-emphasis on the post-tap of the
transmitter buffer.

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)
