Hardware option extends spectrum analyser range
Rohde & Schwarz is expanding the analysis bandwidth of its R&S FSW high end signal and spectrum analyser to 2 GHz with the FSW-B2000 hardware option. This test solution enables R&D users to demodulate extremely wideband signals and analyse them in detail. It means users can measure the EVM values of communications signals or the chirp rate on chirped radar systems.
To analyse a signal with such a large bandwidth, the new option downconverts it to an intermediate frequency, which is then wideband digitised by an R&S RTO oscilloscope. The FSW equalises this digital signal and adjusts the sampling rate. The entire signal path including the oscilloscope is calibrated.
Users control the easy to operate setup via the analyser, which also displays measurement results. Measurement applications such as vector signal analysis or pulse and transient measurements make it possible to analyse the signal in detail.
The performance features offered by the R&S FSW make the instrument ideal for developers of devices and components complying with IEEE 802.11ad, the latest WLAN standard, enabling the transmission of high data rates over short distances. IEEE 802.11ad signals have a symbol rate of 1.76 Gsample/s in single carrier mode and require 2 GHz of analysis bandwidth for demodulation.
