Beschreibung: Frequency Divider and Clock
                                    The Model 113BR is a component instrument in the
Hewlett-Packard frequency and time standard system (see
paragraph 1-8). Instrument specifications are listed in
table 1-1. The Model 113BR indicates time on a standard
clock face and provides 1-pps output pulses or ticks whose
phase can be manually adjusted using a calibrated
front-panel control. In operation,. the phasing control is
adjusted to give time coincidence between the clock tick and
a master timing tick. The time difference between two phase
settings can be read directly from the phasing control and
is used to compute system oscillator frequency.
1-5. The Specification H02 113BR is a standard Model 113BR
which has been tuned for sideral time operation, using an
input frequency of approximately 100.27379091 kc. The tuned
circuits which are affected include T1 through T8.
1-6. In this manual, the Model 113BR Frequency Divider and
Clock is referred to as the “clock”.
1-7. The clock meets the performance requirements of
military specification MIL-E-16400 and is suitable for
mobile operation. Fail-safe operation is provided by using
non-self-starting frequency dividers and a non-self-starting
synchronous clock motor. The clock therefore either
continues to operate without error or ceases operation
completely in case of momentary failure of either the
external power supply or the external frequency standard.
