Signal and Spectrum Analyzer Characterizes Wideband Signals Continuously to 50 GHz

May 6, 2013. Rohde & Schwarz announced it has increased the frequency range of its high-end R&S FSW signal and spectrum analyzer to 50 GHz. The new R&S FSW50 signal and spectrum analyzer serves in the development, testing, verification, and production of transmitters and components such as those used in radar applications and satellite and military communications systems. The analyzer covers the frequency range from 2 Hz through 50 GHz. Using harmonic mixers from Rohde & Schwarz, the frequency range can be extended to 110 GHz.

In addition, Rohde & Schwarz has doubled the analysis bandwidth of the R&S FSW50 from 160 MHz to 320 MHz. This value allows the demodulation of wideband signals such as radar chirps up to 50 GHz. In the past, measuring these kinds of wideband signals often required complicated test setups consisting of a digital oscilloscope and a downconverter. The R&S FSW50 simplifies the test setup, offers wider dynamic range, and is easier to calibrate.

Featuring wide RF dynamic range, high measurement speed, and numerous measurement functions, the R&S FSW50 is suitable for use industrial and university R&D laboratories. Aerospace and defense calibration labs requiring a maximum input frequency of 50 GHz or high repeatability of results will also benefit from the instrument. The low DANL of -164 dBm/Hz in the microwave range with activated preamplifier allows even the smallest of spurious emissions to be detected—such as those found in radar signals. The analyzer offers high sensitivity close to the carrier even at 50 GHz, featuring a phase noise of -114 dBc (Hz) at 10 kHz from the carrier.

The integrated multistandard radio analyzer (MSRA) function of the R&S FSW50 makes it possible to measure spectrum and modulation parameters of differently modulated signals, including their correlation in time. The 12.1” (31-cm) touch-screen interface makes operation convenient, especially for complex measurement tasks. The MultiView function allows users to simultaneously display multiple measurements and different applications on the screen.

The R&S FSW50 signal and spectrum analyzer is available now. The 320-MHz analysis bandwidth will be available soon.
