The HSY Series are broadband frequency sources that exhibit best in industry phase noise performance coupled with the highest channel density available in its class. The YIG based architecture also enhances spectral purity performance coupled with a highly accurate dynamic range of up to +20 dBm and down to -110 dBm. The 1U high form factor offers 1, 2, 3 or 4 channel models; all providing the ultimate in frequency accuracy, while the phase coherent RF outputs provide the ultimate in channel-to-channel stability.
