Introduction. This Keysight Technologies, Inc. application note presents the fundamental measurement principles involved in testing and troubleshooting digital RF communications receivers—particularly those used in digital RF cellular systems. Measurement setups are explained for the various receiver tests, and troubleshooting tips are given.

As the bandwidth B increases, the sensitivity number increases and therefore the receiver becomes less sensitive. (E.g. when the receiver sensitivity goes from -90 dBm to -60 dBm, it has become less sensitive). A ten fold increase in bandwidth – for example from 10 kHz to 100 kHz – reduces the sensitivity by 10 dB.Mute modes. The ew 100 G3 Series offers a choice of two mute modes: RF mute and traditional AF (audio) mute. RF mute stops the transmitter from transmitting on that frequency, which not only mutes the signal (as would AF), but allows another transmitter tuned to the same frequency to then communicate with the receiver.
