The HSY Series from Holzworth are YIG-based RF signal synthesisers that operate from 10 MHz to 3/6/12/24/40 GHz. They are available in 1-, 2-, 3- or 4-channel options, with each channel having an accurate dynamic range from -110 to +20 dBm. The synthesisers provide a frequency step size of 0,001 Hz and have a phase offset resolution of 0,1º and a switching speed of less than 10 ms.
These multi-channel CW signal sources offer excellent phase noise and spectral purity performance. They are ideal for applications such as semiconductor manufacturing, quantum computing and radar test systems where phase coherence and signal purity are critical.
The YIG (yttrium iron garnett)-based, multi-loop PLL architecture dramatically increases the performance beyond existing Holzworth RF synthesisers in terms of phase noise and spectral purity and increases channel-to-channel phase coherency and stability.
Each RF output is driven by a separate, internally loaded synthesiser/attenuator module. Up to four independently tuneable synthesisers can be specified per 1U chassis, allowing for the highest integrated channel density available in its class. With an average power dissipation of less than 20 Watts per channel, the HSY Series is highly efficient.
The signal synthesisers are available in a compact 1U enclosure with SMA connectors and they support USB Type-B, Ethernet, RS-232 and GPIB data I/O control interfaces.
