FSUP signal source analyzer

Rohde & Schwarz, www.rohde-schwarz.com

The R&S FSUP combines a phase-noise test set with a high-performance spectrum analyzer (R&S FSU) in one box that can operate up to 50 GHz. When measuring phase noise, the instrument compares a signal from a device under test with a reference signal source using its internal reference or an external reference. For VCO characterization, the instrument measures VCO tuning characteristics and includes several low-noise DC sources to supply and control the device under test (DUT). A time-domain function measures settling times.

The FSU spectrum analyzer integrated in the instrument allows users to perform measurements on parameters such as adjacent channel power. The FSUP can also measure noise figure with the aid of a noise source and the optional R&S FS K30 noise-measurement software.
