The SignalShark 3320 is a Real-Time Spectrum Analyzer that operates from 8 kHz to 8 GHz. It is capable of detecting, analyzing and classifying a wide range of signals, as well as locating the source of transmissions using either automatic direction finding or TDOA (time difference of arrival) techniques. The instrument uses advanced FFT computations to achieve a 40 MHz real-time instantaneous bandwidth with a 100% probability of intercept (POI) for signals longer than 3.125 µs. The unit also captures the spectrum over the full frequency span of 8 kHz to 8 GHz in a single measurement at the impressively fast scan rate of 50GHz/s.
The 3320 is equipped with an excellent RF front-end delivering outstanding sensitivity and dynamic range. It also provides four switchable RF inputs, which allow several different antennas – covering different frequency bands, for example – to be connected at the same time without the need for a complex switch that conventional single-input analysers require for this purpose.
The analyzer is available in either stand-alone or 19 in. rack-mount versions and can be accessed with remote desktop software via a network and can also be operated locally by means of an external monitor, keyboard and mouse. It provides a very flexible GUI with four task modes to support a wide variety of measurement applications, namely scan mode, real-time spectrum mode, auto DF mode and real-time streaming mode.
