With the new option R&S FSWP-B56G, Rohde & Schwarz has extended the frequency range for absolute phase noise measurements from 50 GHz up to 56 GHz. Done simply by pushing a button, no external converter is needed. These frequencies are needed for satellite communication and for jitter measurements in high-speed digital applications such as ultra-fast LAN IEEE 802.3dj or CEI-224G (Common Electrical I/O).
With the support of external high-end sources as local oscillators it combines the advantage of an easy-to-use signal source analyzer and a high-end phase noise tester. For additive and residual phase noise measurements on amplifiers Rohde & Schwarz has extended the frequency range of the internal signal source up to 54 GHz. In addition, a new and very easy method for noise figure measurements has been added.
In addition, the R&S FSWP features a new marker function “Noise Figure Marker”. Users can measure the noise figure of an amplifier easily, just connecting it between the output of the signal source and input of the R&S FSWP. This easy new method for measuring the small signal noise figure of amplifiers is based just on the phase demodulation same as the phase noise measurement. As the R&S FSWP is equipped with a signal and spectrum analyzer, it delivers both the Y-factor measurement based on noise sources with a calibrated ENR in the spectrum analyzer as well as the new noise figure measurement based on demodulation in the phase noise tester.
