Used Rohde Schwarz FSQ8 Spectrum Analyzer

The R&S FSQ is the solution for all development and production measurement tasks. It offers very low phase noise, unsurpassed low residual EVM, a wide dynamic range and above-average accuracy, making it the ideal high-end measuring instrument for development applications, where tolerances and limit values must often be lower than defined in a standard.
