The HSM Series from Holzworth Instrumentation is a range of RF synthesizer modules that operate from 10 MHz to 6.7 GHz. They are microwave CW sources that are architected on a non-PLL based platform. The digital-analog hybrid design provides excellent phase noise performance and spurious response, which compliment the phase coherent nature of these digital-analog hybrid signal sources.
The modules can be controlled directly via the SPI bus, the Holzworth GUI, a preloaded lookup table, LabVIEW, MATLAB, C++, C#, etc. They have a switching speed of less than 100 ns with phase memory and an onboard precision 100 MHz OCXO. The HSM series is ideal for electronics design, manufacturing test and OEM systems integration applications.
