4.3.4.3.1.1. The FMC+ Test Tab
Figure 22. The FMC+ Test Tab
Use the following controls to select an interface to apply PMA settings, data type and error control.
Port
Allows you to specify which interface to test. The following port test is available:
- FMC+ x8
PMA Setting
This 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
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.
- Bit Error Rate: Calculates the bit error rate of the transmit data stream.
- Insert: Insert 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 counter and Inserted Errors counter to zeros.
Run Control
- TX and RX performance bars: Show the percentage of maximum theoretical data rate that the requested transactions can achieve.
- Start: This control initiates the loopback tests.
- Data Rate: Displays the XCVR type and data rate of each channel.
