Troubleshooting Procedures

3.To examine each sampler’s IF signal, redefine which port and sampler the network analyzer uses for the phase lock. Use the following steps:

a. Redefining to Port 2, sampler a2, press:

PARAMETER [MENU]

{USER 3 a2} then {REDEFINE PARAMETER} {DRIVE}

DRIVE: {PORT 2}

{PHASE LOCK} {a2}

￿{REDEFINE DONE}

Observe the resulting a2 IF trace on the display.

b. Redefining to Port 2, sampler b2, press:

{USER 2 b2} then {REDEFINE PARAMETER} {DRIVE}

DRIVE: {PORT 2}

{PHASE LOCK} {a2}

￿{REDEFINE DONE}

Observe the resulting b2 IF trace on the display.

4.Connect an open (or short) to Port 1 and Port 2. Power is reflected back to b1 and b2 samplers through the coupler.

To check each sampler trace, press:

{USER 1 a1}

{USER 2 b2} {USER 3 a2}

￿{USER 4 b1}

5.Record your results for paths 1 thru 4 ({USER 1} to {USER 4}) in Table 5-6.

NOTE	See Figure 5-10for an RF signal-path 1 trace example. For Option 007, see
	Figure 5-13.
