5.0 HSX SERIES CONFIGURATION GUIDE

5.1 CONFIGURATION SUMMARY

The Holzworth HSX Series multi-channel platform is designed to achieve optimal channel-to-
channel stability across all integrated channel synthiesizers via a conductively cooled, fan-less
enclosure. Specific attention is paid to phase coherency between the independely controllable
channels. Internal channels offer better than -110 dB of channel-channel isolation.
The HSX Series is a unique platform allowing the user to specify custom configurations for a
COTS product. Units are loaded with anywhere from 1 to 4 channels (up to 6GHz). The HSX
Series provides industry leading phase noise and spectral purity performance, as well as
exceptionally high output power dynamic range from +20 to -110 dBm.
Each RF output is driven by a separate, internally loaded synthesizer module. Up to 4
independently tunable synthesizers can be specified per 1U chassis allowing for the highest
integrated channel density available in its class.
Holzworth HSX Series offer the benefits of a proprietary multi-loop based synthesis architecture.
Coupling the multi-loop architecture with a centralized reference distribution subsystem enables
truly phase coherent independently settable channels.
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 channel-to-channel thermal gradients.
Holzworth multi-channel designs are integrated into precision applications that include ATE
systems integration, particle accelerator, timing clocks, satellite position tracking and more.
