K+K KL-3400 is a clock generator for extreme demands for stability and security. Combining several precision oscillators allows to compensate their differences and to recognize faulty oscillators.
The purpose of the K+K KL-3400 Real Time Software Clock is to provide a stable clock signal based on the short term frequency stability of the built-in OCXO, the medium term frequency stability of a set of atomic clocks, and the long term timing accuracy of a GPS timing receiver, which -- within reasonable limits -- will continue its phase track even if one of the contributing clocks fails.
Benefits from the Software Clock are:
The primary realization of the software clock time scale are a 10 MHz output signal plus a 1PPS timing output coherently derived from these 10 MHz. As an option, additional outputs may be provided as needed.
All the components of the K+K KL-3400 Real Time Clock hardware are mounted into a single 19" frame with a width of 84TE and a height of 3HE. It basically consists of
The hardware of the K+K KL-3400 Real Real Time Clock consists of several boards, each with a front panel.Optional generators for additional signals (like 5MHz or 100MHz), distribution amplifiers etc. complete the picture.
A standard PC running Windows is used as a terminal.
The KL-3400 was developed with support from Physikalisch-Technische Bundesanstalt PTB, Germany, with financial support from Federal Ministry of Economics. It is distributed by Lange Electronic, Gerlinden, Germany.
