Analysing an FM signal from audio source to antenna! RF, MPX and audio signals are digitised as soon as they enter the equipment; the only processing done in the equipment is to create the analysis.
From the RF input, this acquisition is done using an accurate high speed converter, directly from the FM transmitter or generator, without mixing. Digitalizing right from the input gives the equipment measurement reproducibility over time, as well as from one device to another: the same signal applied to two devices will give the same result. The accuracy of the digital filters used in this equipment, enables the FM multiplex signal components to be accurately and reproducibly isolated from one another, incurring no time drift.
The calculation power which this equipment puts at the user's disposal, enables all the measurements to be refreshed simultaneously and synchronously, thereby allowing for coherent readings of all the Multiplex FM signal components, while viewing the 4 available spectra and maintaining a review of the decoded RDS.
