Rohde & Schwarz has doubled the analysis bandwidth of its high-end R&S FSW signal and spectrum analyzer from 160 MHz to 320 MHz. The R&S FSW is currently the only signal and spectrum analyzer on the market able to process signals in this bandwidth. This gives the analyzer a competitive edge in a variety of applications related to wideband digital communications and radar systems. 
R&S RTO features an impressive low-noise frontend, high dynamic range ADC, high acquisition and analysis rate and a digital trigger system with extremely low trigger jitter. In addition to automatic jitter measurements, the R&S RTO-K12 jitter analysis option offers a wide range of intelligent functions.
Power analysis requires that users measure voltage and current. For this purpose, Rohde & Schwarz offers high end voltage and current probes and now also the new R&S RT-ZF20 deskew fixture. The deskew fixture makes it easy to measure delay differences, which can then be corrected in the oscilloscope.
Rohde & Schwarz adds the R&S BBA150 for the microwave range to its EMC portfolio. These compact, lightweight amplifiers with their state-of-the-art design are optimized for high frequencies starting at 0.8 GHz. Depending on the setup, the R&S BBA150 can be manually operated via its display and buttons or it can automatically control via a remote control interface or a web browser. 
A product must pass the USB Implementers Forum's compliance tests (USB-IF compliance program). Rohde & Schwarz meets this need with the R&S RTO-K21 USB 2.0 compliance test software for its R&S RTO high-performance oscilloscope. This software offers scenarios for testing USB 2.0 devices (DUT) when functioning as a device, host or hub.
