Holzworth是美国一有专业生产高相位噪声器件与仪器的厂家，产品主要以高相噪为目标，目前主要生产模块射频源、多通道射频源、超高相噪射频源、相位噪声分析仪、高相噪射频微波部件等。

The HSX Series integrates high performance 10MHz to 6GHz, 12GHz and/or 20GHz CW sources inside a 1U enclosure, optimizing rack space. This series of broadband frequency sources exhibit industry leading phase noise and spectral purity performance coupled with a highly accurate dynamic range of +20dBm to -110dBm. The 1U high form factor is available in 1, 2, 3 or 4 channel (independently tunable) models; each providing the ultimate in frequency accuracy, channel-to-channel stability and phase coherency.

Holzworth HSX9000系列多通道射频信号发生器，业界超高相噪水平，目前得到广大用户的认可，特别是在做高精度时钟领域。

Holzworth products are well known for their ultra low phase noise characteristics. All products undergo 100% phase noise performance verification prior to shipment.

SYNTHESIZER CHANNEL PERFORMANCE

The raw data displayed in this section is of the SSB phase noise vs. frequency offset as measured for the HSX9000 Series RF Synthesizers. All data was collected with an output power setting of +10dBm.

Multi-Channel RF Synthesizers

The HSX Series integrates high performance 10MHz to 6GHz, 12GHz and/or 20GHz CW sources inside a 1U enclosure, optimizing rack space. This series of broadband frequency sources exhibit industry leading phase noise and spectral purity performance coupled with a highly accurate dynamic range of +20dBm to -110dBm. The 1U high form factor is available in 1, 2, 3 or 4 channel (independently tunable) models; each providing 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 module. Up to 4 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 17 Watts per channel, the HSX9000 Series is highly efficient.
