Any AiRocks unit can be used as a Spectrum Analyzer when not being used as a Master or Relay unit. In
fact, it may be desirable to dedicate an AiRocks unit as a Spectrum Analyzer for an event to give an
added measure of security knowing where the interfering sources are, and to monitor the transmission
of the Master and nearby Relay unit(s).
The screen below shows the Spectrum Analyzer mode. Transmissions from the Master and any Relay
units are shown in green. Interference is shown is red. The spectrum is divided into 10 discrete channels
which are used by the ARX-900. The blue horizontal indicator lines show peak signal levels in the
channel, while the white indicators show a 10 second average of the signal power in the channel. These
indicators can be reset by pressing the “Reset Peaks” button in the upper left.
