The HSY Series from Holzworth are YIG-based RF Signal Synthesizers that operate from 10 MHz to 3/6/12/20 GHz. They are available in 1 and 2-channel options, with each channel having an accurate dynamic range from -110 to +18 dBm. The synthesizers have a frequency step size of 0.001 Hz, a phase offset resolution of 0.1º, and a switching speed of less than 50 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 coherency and signal purity are critical.
The YIG based (Yttrium Iron Garnett), multi-loop PLL architecture provides the ultimate in frequency accuracy, channel-to-channel stability, and phase coherency. 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. With an average power dissipation of less than 20 Watts per channel, the HSY Series is highly efficient.
The HSY Series RF signal synthesizers are available in a compact, 1U enclosure that measures 15.00 x 17.00 x 1.75 inches and has SMA connectors. They support USB Type-B, Ethernet, RS-232, GPIB data I/O control interfaces.
