Interference can be internal or external, uplink or downlink, and has a direct impact on the quality of service (QoS) of a communication network. FieldFox’s interference analyzer is designed to identify interference signals quickly. Spectrogram and waterfall display detect intermittent signals or monitor signals of interest for longer periods. Signal traces can be recorded into internal memory or external flash memory devices and played back the saved traces for offline processing.

The Spectrogram is a single horizontal line of color-coded power while Waterfall uses a 3-D color-coded display. The functional difference between these two displays is that Spectrogram provides less trace detail than the Waterfall display. However, it also allows more traces to be viewed.

These two displays can NOT be used with Channel Measurements.
