HEATH, Ohio – U.S. Air Force metrology and calibration experts needed signal source analyzers for calibrating phase noise analog and digital modulation test and measurement. They found their solution from Rohde & Schwarz GmbH in Munich.
The Air Force Metrology and Calibration Authority in Heath, Ohio, has ordered signal source analyzers from Rohde & Schwarz for operations in AFMETCAL's precision measurement equipment laboratories and Air Force primary standards laboratory.
The signal source analyzers are for calibration of phase noise analog (AM, FM and PM) and digital modulation measurements. For phase noise measurement Rohde & Schwarz also has provided cross-correlation for sensitivity, flexibility and fast measurement speed all in one box.
The signal source analyzers are based on the Rohde & Schwarz FSWP, a phase noise and voltage-controlled oscillator tester with high sensitivity thanks to extremely low-noise internal sources and cross-correlation.
Due to the low-noise internal local oscillator and a second receive path enabling cross-correlation, it is capable of measuring the phase noise of most commercially available synthesizers and oscillators. The sensitivity increases depending on the number of correlations used. With a the analyzer meets the US Air Force's requirements.
The signal source analyzer has a sensitivity of -166 dBc/Hz at 10 kHz offset at 1 GHz, and measures amplitude noise and phase noise, and displays results simultaneously in a diagram or in separate windows.

The signal source analyzer also is a high-end signal and spectrum analyzer with a pre-selection to 50 GHz and an 80 MHz signal analysis bandwidth for analysis of analog or digital modulated signals like required by the Air Force.
The RF and microwave test and measurement device enables users to switch between different measurement channels. Additional options include pulsed phase noise, noise figure, or ILS/VOR measurements.
