On 28 June, Rohde & Schwarz announced that it has extended the internal analysis bandwidth of its FSW high-end signal and spectrum analyser up to 2GHz with the introduction of the new FSW-B2001. The new unit becomes the first analyser to offer bandwidth to this level.
Developers of 5G radio access technologies, high-end radar systems and automotive applications need a very large bandwidth to analyse wideband signals. The FSW-B2001 solution enables R&D users to investigate wideband signals in detail without the need for an external digitiser. It provides 14-bit ADC resolution and wide dynamic range, characterised by excellent SFDR figures, for example -65 dBc for 1200MHz bandwidth. This translates directly into outstanding signal analysis performance. The instrument can measure an EVM of around -40.0 dB error vector magnitude with an OFDM signal (792 MHz BW, 300 kHz spacing, 64QAM, 4096 FFT) at 28 GHz.
Bandwidth up to 2,000MHz facilitates R&D for next generation mobile standards, as well as characterisation of wideband amplifiers for 5G. Aerospace and defence developers will be able to use the 2GHz analysis bandwidth to measure radar pulses down to nanosecond widths, and analyse frequency-agile radar or -hopping radio systems. Automotive R&D applications include characterization of FM carrier wave signals for radar applications, and ultrawide bandwidth signals such as those used in keyless entry systems.
