5.3.7. The FMCB Tab
The FMCB tab allows you to perform loopback tests on the FMCB port.
Figure 41. The FMCB Tab
The following sections describe the controls on the FMCB tab.
Displays the following status information during a loopback test:
- PLL Lock: Shows the PLL locked or unlocked state.
- Pattern Sync: Shows the pattern synced or not synced state. The pattern is considered synced when the start of the data sequence is detected.
- Details: Shows the PLL lock and pattern status:
Allows you to specify which interface to test. The following port tests are available:
Allows you to make changes to the PMA paratmeters 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.
- 1st Post: Specifies the amount of pre-emphasis on the first post tap of the transmitter buffer.
- Equalizer: Specifies the CLTE EQ Gain for the receiver.
- AC Gain: Specifies the CLTE AC Gain for the receiver.
- VGA: Specifies the VGA gain for the receiver.
Specifies the type of data contained in the transactions. The following data types are available for analysis.
- PRBS 7: Selects pseudo-random 7-bit sequences.
- PRBS 15: Selects pseudo-random 15-bit sequences.
- PRBS 23: Selects pseudo-random 23-bit sequences.
- PRBS 31: Selects pseudo-random 31-bit sequences.
- HF: Selects highest frequency divide-by-2 data pattern 10101010.
- LF: Selects lowest frequency divide-by-33 data pattern.
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: Inserts a one-word error into the transmit data stream each time you click the button. Insert is enabled only during transaction performance analysis.
- Clear: Resets the Detected Errors counter and Inserted Errors counter to zero.
- TX and RX performance bars: Show the percentage of maximum theoretical data rate that the requested transactions are able to achieve.
- Start: this control initates the loopback tests.
- Tx (Mbps) and Rx (Mbps): Show the number of bytes of data analyzed per second.
- Data Rate: Shows the data rate for each link.
