Analog RX Diagnostic Results

Figure 7-188 Analog Rx Diagnostic Results
The DRX column numbers refer to "DRX Board number, Nathan ASIC, channel within Nathan."
For example: If under the DRX column, you see 1,2,0 - this is referring to DRX1, Nathan ASIC
number 0, channel 0 within Nathan.
GRX64 passes signal to DRX1. GRX128 passes signals to DRX2 and DRX3. The Analog Receive tests
may be run with the Front Planes removed. There is Front Plane failure mode which can cause this
diagnostic to fail.
For service, the relevant information is the board number. If any channel fails, the board in that path can
be identified.
