EADS / Racal / Dana 6061A Synthesized Signal Generator

The EADS/Racal/Dana 6061A is a synthesized signal generator delivering precise RF signal generation from 10 kHz to 1050 MHz with 10 Hz frequency resolution. Purpose-built for receiver testing, component evaluation, and general RF applications, this VXIbus module combines signal generation with integrated analog and digital I/O channels. Superior phase noise performance—typical –123 dBc/Hz at 20 kHz offset from a 500 MHz carrier—distinguishes the 6061A from related models, making it especially valuable for low-noise receiver characterization.
