5.0 HS9000B SERIES CONFIGURATION GUIDE

5.1 CONFIGURATION SUMMARY

The Holzworth HS9000B 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.
The HS9000B Series is a unique platform allowing the user to specify custom configurations for a
COTS product. Units are loaded with anywhere from 1 to 8 channels (up to 6.7GHz), with the
additional flexibility to specify each channel‟s frequency limits and performance options. The result
is a high performance, multi-channel synthesizer that is tailored to an application with an optimal
price point.
Each RF output is driven by a separate, internally loaded synthesizer module. Up to 8
independently tunable synthesizers can be specified per 1U chassis allowing for the highest
integrated channel density available in its class. With an average power dissipation of 7 Watts per
channel, the HS9000B series is highly efficient.
Holzworth Multi-channel RF Synthesizers offer the benefits of a proprietary NON-PLL based
synthesis architecture. Coupling the NON-PLL architecture with a centralized reference distribution
subsystem enables truly phase coherent, independently settable channels.
Different from traditional PLL based synthesizers, Holzworth‟s proprietary 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 range from particle
accelerator timing clocks to satellite position tracking. Due to the necessity for the ultimate in signal
stability, Holzworth synthesizers also come standard with thermal monitor outputs to track the
relative channel temperature of each loaded channel.
