Receiver Diagnostic Signal Tracing

Use the following information to trace the received signal through the receiver chain:
• An RF signal generator is recommended; however, an Agilent call box 8960 may
also be used. For the 8960, press the CALL SETUP key, soft key Active Cell, and
then select CW.
• Inject a CW signal for PCS (1960.3 MHz) or Cell (881.82 MHz) at a fixed –65dBm
power level.
• Take measurements with the AAS-10 probe.
• Signal levels are approximate, and accuracy may be ± 2dB or more, depending on
position and grounding of probe.
