R&S ramps up bandwidth of FSW spectrum analysers
Rohde & Schwarz has released the FSW-B500 hardware option for its FSW signal and spectrum analyser products. The hardware option increases the bandwidth of the products to 500MHz from its previous limit of 320MHz. The option has potential applications in radar and satellite technology, as well as wireless data networks including WiFi and Beyond 4G (5G).
The increased bandwidth enables users to perform measurements hitherto not possible. For instance, they now can determine pulse rise and decay times of just 3ns and measure very short pulses lengths of 8ns, opening up new application options in automotive radar system development. Thus, users can completely survey radar chirps at bandwidths of up to 500MHz. Another possible application would be the analysis of frequency hopping sequences in military radio systems. Developers and researchers in the area of satellite radio also can characterise the components of future transponder generations with the maximum bandwidth.
An FSW signal analyser with the 500MHz option enables developers of RF amplifiers for mobile networks or for WiFi equipment to measure digital pre-emphasis of amplifiers for a bandwidth of up to 160MHz as required for the wireless LAN standard IEEE 802.11ac. Hitherto, recording signals with such a large bandwidth required complex setups of a digital oscilloscope and a down converter.
The FSW-500 is available for all instruments of the FSW product family and thus, for frequencies of up to 67GHz. By default, Rohde and Schwarz intends to sell it as an option for new instruments. It is also possible to retrofit existing installations under certain conditions through the R&S field service support, the company said.
