1.3 Purpose of Equipment
The Model 800 Series is a family of Time Code instruments designed around a versatile
microprocessor. The three basic operating modes of these instruments are:
1. As a Time Code Generator that accumulates time from an entered starting time and
then provides various outputs based on the accumulated time.
2. As a Time Code Translator that deciphers serial time codes from some external source
and provides various outputs based on the decoded time. The Translator operates in
both the forward and reverse directions.
3. As a Synchronized Generator it is derived from the input time code and is
phase-locked to the input code. If the input fails, the generator continues to update
using its time base as the reference. Further, the internal oscillator is disciplined to the
frequency of the input code, which further enhances the performance of the unit during
periods of input code failure.
The various operating modes are optional and are supplied if they are marked (X) in the
Table of Contents.
