CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA hardware prototype of a vector spectrum analyzer, which is based on an aliasing-free randomized sampling strategy, has been fully designed and implemented. The instrument exploits a couple of identical independently programmable acquisition channels, capable of providing input signal samples at instants that can be very closed onto the time-axis (tens of ps), with a maximum single channel throughput rate of 500 kS/s. This allows for the practical implementation of the randomized periodic sampling with uniform jitter scheme the instrument is based on. In addition, accurate 12-bit ADCs can be adopted within each channel, which are essential in order to apply to the signal samples the numerical algorithms devoted to the estimation of input harmonic components.
