Measuring the RX module manually using Oscilloscope and Spectrum Analyzer

Spectrum Analyzer level values depend on the probe type and should be validated using a

known good NHL-10 sample. The levels that are given here are measured using a high fre-

quency probe.

Measuring with Oscilloscope on RXINN or RXQINN (J606 –608) and RXID or RXQD (J211 –

J212) is recommended only if RSSI reading does not provide enough information. No dedicat-

ed test points exist for RX I/Q signals, however, they can be accessed by probing on a via hole

plating.

• Start Phoenix Service Software and establish a connection to the phone.

• Select File -> Scan Product Ctrl R.

• Select Testing -> RF controls.

• Select Band -> GSM900.

• Active unit -> RX.
