Our new phase noise analyzer FSWP from Rohde & Schwarz has just arrived. With this measurement device the phase noise (and also the amplitude noise) of both one-port and two-port devices under test (DUT) can be measured. One-port measurements are particularly necessary for the noise characterization of the oscillators used for the excitation of our sensors. However, the main feature of this device is the additional radio frequency (RF) source for so-called additive phase noise measurements, e.g. two-port measurements. Thus, we are now able to comprehensively analyze our new surface acoustic wave (SAW) magnetic field sensors [Kit 2018] regarding their noise behaviour. Last but not least the FSWP greatly supports the development of low-noise sensor electronics.
