Signal and spectrum analyser for wideband signals to 50 GHz
Rohde & Schwarz’ FSW50 signal and spectrum analyser covers the frequency range from 2 Hz through 50 GHz. Using harmonic mixers, the frequency range can be extended to 110 GHz. There is also there is doubled analysis bandwidth from 160 MHz to 320 MHz. This value, which the company says is unmatched in the industry, 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 FSW50 simplifies the test setup and it also offers significantly wider dynamic range and is easier to calibrate.
With wide RF dynamic range, high measurement speed and numerous measurement functions, the FSW50 is a microwave analyser that is particularly useful in industrial and university R&D laboratories. Aerospace and defence calibration labs requiring a maximum input frequency of 50 GHz or high repeatability of results will also use the instrument. The low DANL of -164 dBm/Hz in the microwave range with activated preamplifier allows even the smallest of spurious emissions, such as those found in radar signals, to be detected. The analyser 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 analyser (MSRA) function of the FSW50 makes it possible to measure spectrum and modulation parameters of differently modulated signals, including their correlation in time. This makes it very easy to analyse how different signals affect each other and provides an efficient means of identifying errors caused by this interaction. The 12.1” (31 cm) touchscreen interface simplifies configuring the instrument for complex measurement tasks. The MultiView function allows users to simultaneously display multiple measurements and different applications on the screen. The high-end FSW50 signal and spectrum analyser is now available; with the 320 MHz analysis bandwidth option available soon.
