Receiver RF Test Points

For the test points in Figure 14, an external signal source of –96 dBm was added to the RF

input. Set LNA GAIN STATE = 4.The signal was then traced throughout the receiver chains.

An Agilent8960 call box is recommended. Set the band and channel as ETS set. Set the cell

power = - 96dBm. Watch the received power of the DSPM Rfc RXTX. Measurements were

taken with the RF Probe. Signal levels are approximate, and the accuracy may be +/- 2 dB or

more depending on the probe position and grounding.
