Hewlett Packard 113BR Frequency Divider and Clock, 7" high, ...

Hewlett Packard 113BR Frequency Divider and Clock, 7" high, 18" wide, depth 18" ** A precision 19” rack mounted electronic timing instrument manufactured by Hewlett Packard in the early 1960s as part of professional frequency and time standard systems The unit accepts a highly stable reference frequency, typically derived from a precision oscillator, and divides this signal down to provide accurately timed outputs including one-second pulses for synchronisation and measurement applications. A precision analogue clock display provides a visual indication of the derived time reference, allowing comparison and adjustment of frequency standards Designed for use in laboratories, communications facilities and scientific establishments, the 113BR represents the high-precision electronic timekeeping technology developed during the transition from quartz standards to atomic frequency references ** From the David Read Collection
