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.
