Rubidium clocks target high-performance apps

Members of the iReference+ series, the GNSSource-2500 and RbSource-1500 GPS/GNSS rubidium primary reference clock sources offer GPS/GNSS-synchronized 1-pps timing signals and 10-MHz frequency signals for high-precision lab equipment testing, measurement and calibration applications. These new products offer advanced timing and frequency capabilities in a compact, 1U package, thanks to the patented SmarTiming+ GPS/GNSS disciplining technology, offering leading-edge 1-ns resolution with a smart, auto-adaptive temperature and GPS noise compensation in real time. The temperature compensation is performed at 0.1°C resolution, whereas the GPS/GNSS noise compensation is performed with a variable loop time constant of 1 to 100,000 seconds, depending on the GPS/GNSS signal noise level.

The RBSource-1500 integrates the smart LNRClok Rubidium (Rb) clock and the SmarTiming+ GPS/GNSS disciplining technology, allowing the user to seamlessly feed an external, in-house GPS/GNSS reference system to the Rb clock. Control and monitoring is provided through the RS-232 interface. For users without an in-house GPS/GNSS reference standard, the GNSSource-2500 includes an integrated GPS/GNSS receiver. (RBSource-1500, $2,995; GNSSource-2500, $4,995 — available now.)
