Simplified Reference Path Block Diagram

If the 10 MHz signal is present, then this verifies the reference path
through the CDMA Generator Reference and the Reference (A2A22)
assemblies.

NOTE

There are other functions on these assemblies that are NOT verified.

CDMA Generator Reference (A2A100) Assembly Verification

1. Turn the Test Set off and remove the external cover.

2. Remove the bottom cover and verify that the cable is connected

between the EXT REF IN connector and J17 on the CDMA
Generator Reference assembly.

3. Turn the Test Set on and verify that a 10 MHz signal is present on

J15 of the CDMA Generator Reference assembly.

If no signal or a poor signal appears at this connector, then the
CDMA Generator Reference assembly is faulty.

4. Turn the Test Set off and remove the top covers.

5. Use screwdrivers to remove the Reference assembly.

6. Turn the Test Set on and verify that a 10 MHz signal is present on

pin 20 of J63 and pin 19 of J18. This is the reference signal from the
CDMA Generator Reference (A2A100) assembly.

If the 10 MHz signal is not present at all, then the CDMA Generator
Reference (A2A100) assembly is faulty.

If the signal is present on pin 20 but not pin 19, then the Motherboard
(A2A1) assembly is faulty (open or short).
