Signal/spectrum analyser expands measurement bandwidth to 500 MHz

January 16, 2014 // By Graham Prophet
Rohde & Schwarz has expanded the analysis bandwidth of its FSW high-end signal and spectrum analysers. From a previous high point of 320 MHz, the company says it is the first T&M supplier to offer analysis bandwidth of 500 MHz.

The FSW-B500 hardware option is available for all analysers in the R&S FSW family, taking coverage 67 GHz. This, according to R&S, opens up new R&D applications, including measurement tasks in radar or satellite applications as well as for tests on fast wireless connections such as WLAN or Beyond 4G (5G).

The large analysis bandwidth enables users to test pulse rise and fall times from approximately 3 nsec or very short pulses from 8 nsec pulse width. The analyser can therefore be used in the development of radar systems for automotive applications. Users can fully record and measure radar chirps with up to 500 MHz bandwidth. Hopping sequences in frequency-agile communications systems such as tactical radios can also be analysed. Researchers working on satellite applications will be able to characterise components for future transponder generations, as well as components for microwave links.

The R&S FSW also offers developers of RF amplifiers for mobile radio or WLAN the ability to measure digital predistortion of amplifiers with up to 160 MHz bandwidth, as required for WLAN 802.11ac signals.
