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: Routes signals between the transmitter and the receiver.
• VOD: Specifies the voltage output differential of the transmitter buffer.
• Pre-emphasis tap:
— 1st pre: Specifies the amount of pre-emphasis on the pre-tap of the
transmitter buffer.
— 2nd pre: Specifies the amount of pre-emphasis on the second pre-tap of the
transmitter buffer.
— 1st post: Specifies the amount of pre-emphasis on the first post tap of the
transmitter buffer.
— 2nd post: Specifies the amount of pre-emphasis on the second post tap of the
transmitter buffer.
• Equalizer: Specifies the AC gain setting for the receiver equalizer in four stage
mode.
• DC gain: Specifies the DC gain setting for the receiver equalizer in four stage
mode.
• VGA: Specifies the VGA gain value.
Data Type
Specifies the type of data contained in the transactions. The following data types are
available for analysis:
