In Case of Difficulty
1. Check the flexible RF cable (W8, as shown in Figure 2-65) between the R sampler
assembly (A4) and the phase lock assembly. Make sure it is connected between A11J1
(PL IF IN) and 1st IF Out.
CAUTION Do not push cable W8 down next to the A11 phase lock assembly.

2. Using an ohmmeter, verify that the RF cable is not open. In addition, examine both the
cable connectors: measure the resistance between the center pin and the cable
connector and make sure it is not close to zero.
3. Check the R sampler by substituting it with the B sampler (A6).
a. Move cable W8 to the B sampler (A6), as shown in Figure 2-66.
