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.
