7-7-4-3 Board-Level EQ Diagnostics
• All Board-Level EQ Diags: More of the SCB is utilized. Specifically, this diagnostic tests the
following SCB functions:
- PCI Bridge
- Clock generation
- Scan Bus generation
- TxSync generation
- RxSync generation
- Image Port
In terms of EQ functionality, what are not tested with this configuration, are any abilities to
communicate with the TD's, XDIF, or RF Amplifier boards. These functions will be tested in other
diagnostics.
The following subsections outline the Board-Level EQ Diagnostics.
• EQ PCI Interface Diag: Tests the PCI Interface.
NOTE: A preferred test strategy for the PCI 9054 Interface is detailed in Section 7-8.
• EQ Memory Diag: Tests all of the on-board memory, including registers.
NOTE: Guidelines in Section 7-9 will enumerate the memory locations.
