A 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.

Abstract

A 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.
