Rohde & Schwarz has extended the analysis bandwidth of its high-end FSW signal and spectrum analyzer from 160 MHz to 320 MHz, allowing the instrument to be used in a variety of applications related to wideband digital communications and radar systems.
Engineers can use the FSW to analyze radar signals with very short pulses of less than 10 ns or wideband signals in radar systems, such as automotive CW or pulsed radar. The FSW can also test multistandard radio base stations and perform modulation analysis on radio links with a channel bandwidth of 250 MHz.
Models in the FSW series offer frequency ranges from 2 Hz to 8 GHz, 13.6 GHz, 26.5 GHz, 43.5 GHz, and 50 GHz (up to 110 GHz with external mixers). Along with the wide analysis bandwidth of up to 320 MHz, the analyzers provide a dynamic range of –88 dBc (with noise cancellation) and low phase noise of –137 dBc (1 Hz) at a 10-kHz offset (1 GHz carrier).
Users can upgrade their FSW analyzer from the 160-MHz to 320-MHz analysis bandwidth by entering a key code. No hardware modification is necessary.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
