Rohde & Schwarz expands signal analyser for automotive R&D

Rohde & Schwarz FSW signal and spectrum analyser

Rohde & Schwarz is expanding the internal analysis bandwidth of its FSW high-end signal and spectrum analyser up to 2GHz by introducing the FSW-B2001 option. This lets R&D users investigate wideband signals in detail without the need for an external digitiser.

The option provides 14bit ADC resolution and wide dynamic range, characterised by the SFDR figures, for example -65dBc for 1200MHz bandwidth. This translates directly into signal analysis performance.

The instrument can measure an EVM of around -40dB error vector magnitude with an OFDM signal – 792MHz bandwidth, 300kHz spacing, 64QAM, 4096 FFT – at 28GHz. 

Bandwidth up to 2000MHz facilitates research and development for next generation mobile standards, as well as characterisation of wideband amplifiers for 5G.

Automotive R&D applications include characterisation of FM carrier wave signals for radar applications, and ultra-wide bandwidth signals such as those used in keyless entry systems.

Aerospace and defence developers can use the 2GHz analysis bandwidth to measure radar pulses down to nanosecond widths, and analyse frequency-agile radar or hopping radio systems.

The option for the FSW43 and FSW50 high-end signal and spectrum analysers with frequency ranges up to 43.5 and 50GHz, respectively, is now available. FSWs already equipped with 1200MHz internal analysis bandwidth – option R&S FSW-B1200 – can be readily upgraded via a key code.
