The HSX Series was developed to be one of the cleanest CW sources available. Phase noise performance, spurious rejection and harmonic/sub-harmonic rejection were the primary focal points during the development cycle. The result is a high performing, broadband CW source.
The HSX Series was initially released as a 10 MHz to 6 GHz CW source with subsequent models operating to 10 and 20 GHz. This series of broadband frequency sources exhibit industry leading phase noise and spectral purity performance coupled with a highly accurate dynamic range of +18 to -110 dBm. The 1U high form factor will be available in 1, 2, 3 or 4 channel models; all providing the ultimate in frequency accuracy, channel-to-channel stability and phase coherent channels. The 10 and 20 GHz models are anticipated by early 2015.
Phase noise is a critical performance parameter for high speed communications systems, subsystems, components and chipsets. The phase noise performance of the HSX Series is derived from years of development of proprietary techniques that optimize both close-in phase noise (long term stability) and far-from-the carrier phase noise (instantaneous stability), while maintaining true phase coherency.
At 6 GHz, the phase noise is -86 dBc/Hz at 10 Hz offset, -126 dBc/Hz at 10 kHz offset and -138 dBc/Hz at 10 MHz offset. Phase noise at 1 GHz is -144 dBc/Hz at 10 kHz offset. Harmonics are well below -40 dBc and all spurious artifacts are less than -87 dBc.
