Decodio extended its wide range of measurement functions with new features and modules to provide measurement and analysis capabilities inline with ITU requirements defined in ITU R SM.328, 377, 443, 854, 1600 and 1880. This includes tools for manual signal analysis like measurement-cursors for different displays, as well as semi-automatic functions for spectrum-occupancy measurement and signal parameter estimation.
DECODIO RED receives a wideband signal from a connected receiver or from a replayed file (e.g. .wav/.rf64, raw or in HDF5/ITU SM.2117). Narrowband signals are extracted and used for further analysis. Their raw IQ data is used as source for different displays like “time domain” to measure burst durations, zero-crossing for symbol-rate estimation, autocorrelation, DFT or cepstrum. Signal cursors are used to measure and display the estimated values. Decodio RED is capable of importing spectrum markers with center frequency, bandwidth and description from various spectrum management databases. Narrowband IQ-streams in Decodio’s ITU Measurement module are used to estimate the FM Deviation, AM Modulation depth as well as the signal bandwidth based on the x dB and ß% methods in one single step. These measurements can be performed for several channels in parallel. Thanks to the open interfaces, it can interact with 3rd party systems for radio regulation and spectrum management.
