Spectral analysis in baseband of to 6 Ghz, with maximum sampling frequency of 20 Gsa/s. The analysis can be directly performed in hardware, using spectral analyzers, or using external software, after adequate sampling. Additionally, analyses in the 3 Hz – 50 GHz and 75 GHz – 110 GHz bands can be performed. If done in real time, these analyses will be limited to a 160 MHz analysis bandwidth. In the 30 KHz – 6.5 GHz band the equipment is portable, thus allowing its easy remote deployment.
