For many years, Noise XT has only provided Phase Noise Analyzers but their designs always required a really low noise reference source. Today, those excellent sources are available as standalone products so anyone can benefit from their unique performance.
The LNS synthesizer has a typical phase noise of -132 dBc/Hz at 10 kHz offset for a 10 GHz output and the SLC has an amazing -178dBc/Hz noise floor at 100kHz offset for a 10 MHz output frequency. Both synthesizers are wideband sources with mHz frequency resolution.
The new PNG-A is a « one of a kind » instrument that ease all phase noise analyzers calibration. This is a pure digital noise source.
