Option extends analyser internal bandwidth to 2GHz

Posted By : Mick Elliott

The internal analysis bandwidth of Rohde & Schwarz’s FSW high-end signal and spectrum analyser has been extended up to 2GHz by introducing the R&S FSW-B2001 option. This test solution enables R&D users to investigate wideband signals in detail without the need for an external digitiser.

The option provides 14-bit ADC resolution and wide dynamic range, characterized by excellent SFDR figures, for example -65 dBc for 1200 MHz bandwidth.

This translates directly into outstanding signal analysis performance.

The instrument can measure an EVM of around -40.0dB error vector magnitude with an OFDM signal (792MHz BW, 300kHz spacing, 64QAM, 4096 FFT) at 28GHz.

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

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

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.

The R&S FSW-B2001 option for the R&S FSW43 and R&S FSW50 high-end signal and spectrum analysers with frequency ranges up to 43.5GHz and 50GHz is now available from Rohde & Schwarz. In addition, those R&S FSWs already equipped with 1200MHz internal analysis bandwidth (option R&S FSW-B1200) are readily upgraded via a key code.
