Rohde & Schwarz is expanding the internal analysis bandwidth of its R&S FSW high-end signal and spectrum analyzer to 2 GHz by introducing the new R&S FSW-B2001 option. This test solution enables R&D users to investigate wideband signals without an external digitizer.

The R&S FSW-B2001 option provides 14-bit ADC resolution and wide dynamic range, characterized by excellent spurious-free dynamic range (SFDR): −65 dBc for 1200 MHz bandwidth, for example. This translates into outstanding signal analysis performance. The instrument can measure an error vector magnitude (EVM) of around −40 dB with an OFDM signal compriing 792 MHz bandwidth, 300 kHz spacing, 64-QAM and 4096 FFT at 28 GHz.

Bandwidth up to 2 GHz facilitates R&D for next generation mobile standards, as well as characterization of wideband amplifiers for 5G. Aerospace and defense developers will be able to use the 2 GHz analysis bandwidth to measure radar pulses down to nanosecond widths and analyze frequency-agile radar or frequency hopping radio systems. Automotive R&D applications include characterizing FM carrier wave signals for radar applications and ultrawide 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 analyzers, with frequency ranges up to 43.5 and 50 GHz, is now available, while those R&S FSWs already equipped with 1200 MHz internal analysis bandwidth (option R&S FSW-B1200) can be upgraded with a key code.
