The HSY9000 Series RF synthesizers offer industry-leading phase noise and spectral purity performance as a multichannel CW signal source. The compact 1U chassis allows for anywhere from 1 to 2 independently tunable channels (frequency / phase offset / amplitude) to optimize channel density within test system racks where real estate is limited. Application specific frequency options can be configured to cover combinations of 10 MHz to 3 GHz, 6 GHz, 12 GHz, and 20 GHz. Each broadband channel output provides an accurate dynamic range of up to +18 dBm to -110 dBm. Holzworth’s unique multi-loop architecture provides the ultimate in frequency accuracy, channel-to-channel stability, and phase coherency.
Fully Independent Channels
Each RF output is driven by a separate, internally loaded synthesizer/attenuator module. Up to 2 independently tunable synthesizers can be specified per 1U chassis allowing for the highest integrated channel density available in its class.
Phase Coherent Channels
Holzworth HSY9000 Series RF synthesizers offer the performance benefits of a proprietary YIG-based, multi-loop architecture with a centralized reference distribution subsystem, which maintains a tight phase coherent relationship across all integrated channels.
The Ultimate In Channel-to-channel Stability
Different from traditional PLL-based synthesizers, Holzworth’s proprietary multi-loop architecture creates precisely synthesized signals that exhibit both instantaneous and long-term stability. Temperature variations between the channels remain the only contribution to drift. The thermally optimized, fan-less chassis was specifically developed for maintaining the lowest possible thermal gradients from channel-to-channel. Channel specific thermal monitoring is available for tracking the relative channel temperature of each loaded synthesizer module.
