Receiver Diagnostic Signal Tracing

Use the following steps to trace a receiver signal.
1. Inject an external signal source of –25dBm into the RF input. An Agilent call box
8960 is recommended.
2. Press the Call Setup button, press the Active Cell soft button, and select CW.
3. Inject a CW signal for PCS (1960MHz) or Cell/AMPS (881.52MHz) at a fixed
–25dBm power level.

Receiver IF RF

The test point measurements were taken using an AAS-10 probe. Signal levels are
approximate, and accuracy may be +/- 2dB or more, depending on the position of the
grounding probe.
