Products - PHS8500 M

The PHS8500 Family represents THE LOWEST PHASE NOISE synthesizer family available anywhere. Our synthesizer product families are the 8300, 8340, 8400, and 8500. The 8300 and the 8340 are Fractional – N Phase Locked Loop (PLL) models, and the 8400 and 8500 are Integer – N PLL models, which results in no so called fractional spurs. Our instruments are protected under US Patents 8611845, 8749282, and 9134355, and a number of other patents that are pending. As can be seen from the Summary Parameters our instrument families represent a wide range of performance. In addition, each instrument is available in one or more of three models, the M for modular, with lowest power consumption, the B for Benchtop, which allows addition of higher power and closed loop leveling capabilities, and the H for Handheld, which allows for Field use, especially when equipped with the available optional battery.

The PHS8500 M, B, and H are INTEGER SYNTHESIS based PLL Synthesizers. They do not exhibit any fractional spurious outputs such as Fractional-N based synthesizers do.

The 8500 Family is available in the Modular 8400M and the Benchtop 8400B Single Output and Multiple output formats. The Handheld version is available with Battery Option in certain Models. Please contact Pronghorn with your specific requirement.
