• QSFPDD0 x8
• QSFPDD1 x8
• QSFPDD2 x8
• QSFPDD3 x8
PMA Setting
The PMA Setting control 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)
