The CsIII by Microsemi is a lightweight, compact, and cost-effective cesium beam atomic frequency standard. It weighs less than 30 pounds (13.5 kg) and features a portable design suitable for standard 2U 19-inch rack mounting. It offers 5MHz and 10MHz sine wave outputs, 1 TTL output at 10MHz, 1 sync input for 1PPS, and 1 1PPS output, with an optional T1/E1 output.
The CsIII meets the requirements for a primary frequency standard and calibration and is widely applicable in various fields such as satellite tracking stations, positioning and navigation, broadcast communications, and more. Its performance makes it suitable for laboratory standards, satellite communication terminals, mobile communication systems, and a wide range of testing and measurement applications.
