The R&S FSW67 from Rohde & Schwarz is a new high-end signal and spectrum analyser with a frequency range up to 67GHz, plus an integrated preamplifier up to 67 GHz and an analysis bandwidth as high as 320MHz. The analyser helps developers perform complex measurement tasks in the microwave range for aerospace & defenc e applications and wireless communications.

It is the only instrument on the market to cover the frequency range from 2 Hz to 67 GHz in a single sweep. The analyser eliminates the need for external harmonic mixers and therefore requires no complex cabling. Image frequencies and other spurious emissions caused by harmonic mixing are suppressed.

The analysis bandwidth of up to 320 MHz enables the anslyser to measure wideband, hopping and chirp signals. Until now, this required complicated test setups consisting of a digital oscilloscope and a down converter, for example.

Users can now easily perform spectrum measurements and modulation measurements in the 60 GHz band. The analyser can meet applications in the development, testing, verification and production of transmitters and components for radar applications, satellite and military communications systems. It also offers assistance when performing development tasks relating to fast wireless communications based, for example, on WiGig (IEEE 802.11ad) or WirelessHD.

Its integrated preamplifier up to 67GHz makes it very sensitive even in this high frequency range. The smallest of spurious will be detected, and noise figures of components will be measured with high precision. Featuring a phase noise of -111dBc (Hz) at 10kHz offset from the carrier at 67GHz, the analyser offers a high dynamic range even for measurements close to the carrier. This keeps inherent instrument errors especially low during signal analysis.

The integrated multistandard radio analyser (MSRA) measures spectrum and modulation parameters of signals with different modulations simultaneously, and also correlates these signals in time. With the MSRA function, users can efficiently analyse how and why different signals affect each other. The 12.1in. (31cm) touchscreen interface makes operation very convenient, especially for complex measurement tasks. The MultiView function allows users to simultaneously display multiple measurements and applications.
