Characterise wideband and pulsed signals continuously up to 67 GHz

October 21, 2013 // By Graham Prophet
FSW67, recently announced by Rohde & Schwarz, is a high-end signal and spectrum analyser with frequency range up to 67 GHz, plus an integrated preamplifier up to 67 GHz and an analysis bandwidth as high as 320 MHz.

The analyser helps developers perform complex measurement tasks in the microwave range for aerospace and defense applications and wireless communications. R&S says it is the only instrument on the market to cover the frequency range from 2 Hz to 67 GHz in a single sweep. The instrument simplifies test setups, eliminating external harmonic mixers and complex cabling. Image frequencies and other spurious emissions caused by harmonic mixing are suppressed.

Thanks to its unique analysis bandwidth of up to 320 MHz, the FSW67 also measures wideband, hopping and chirp signals. Until now, this required complicated test setups consisting of a digital oscilloscope and a downconverter, for example.

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

The FSW67's integrated preamplifier operating up to 67 GHz makes it very sensitive even in this high frequency range to detect small spuria and to measure noise figures of components with high precision. Featuring a phase noise of -111 dBc (Hz) at 10 kHz offset from the carrier at 67 GHz,
the analyser offers a high dynamic range even for measurements close to the carrier.

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. There is a 12.1 in. (31 cm) touchscreen interface, with MultiView function.
