The R&S FSQ Signal Analyzers are high-end, high performance analyzers that operate from 20 Hz to 40 GHz (3.6/8/26.5/40 GHz Models available). They have a 28 MHz signal analysis bandwidth which can be extended to 120 MHz if required. It has a very low phase noise, 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.
