Communications test specialist Rohde & Schwarz has expanded the analysis bandwidth of the FSW signal and spectrum analyzer to 2GHz with the FSW-B2000 hardware option. This enables users to demodulate extremely wideband signals and to analyse them in detail.
To analyse large bandwidth signals, the FSW downconverts the input to an intermediate frequency, which is then wideband digitised by an RTO oscilloscope. The FSW equalises this digital signal and adjusts the sampling rate. According to the company, the entire signal path, including the oscilloscope, is calibrated.
Users control setup via the analyser, which also displays measurement results. FSW measurement applications, such as vector signal analysis or pulse and transient measurements, make it possible to analyse the signal in detail.
The company claims there is no other instrument on the market that combines such a large analysis bandwidth with the ability to handle frequencies of up to 67GHz. This ability, it adds, could allow user to measure the EVM values of communications signals or the chirp rate on chirped radar systems.
