MODEL 5345A FREQUENCY TIME MEASUREMENT SYSTEM
(14 CREDIT HOURS)
INTRODUCTION
You, as a calibration specialist, face one of the most demanding, yet
rewarding, careers to be offered by the military. Electronics technology,
already a vast field, is expanding by leaps and bounds.
Test equipment
which is considered state-of-the-art today is doomed to early obsolescence
due to extremely rapid technological discoveries and advances. The only way
for you to maintain your proficiency and effectiveness is by continually
staying abreast of these technological developments.
While the Model 5245L electronic counter is a very versatile and
precise instrument, it does not provide the increased accuracy demanded for
some of the sophisticated systems in the Army's current inventory.
This
counter is being phased out through attrition and is replaced by the Model
5345A frequency time measurement system. The Model 5345A is equipped with a
plug-in adapter which permits its use with 5245L plug-ins, providing less
uncertainty and greater accuracy.
The assumption has been made that you possess at least a basic
familiarity with counter theory.
With that in mind, the first lesson is
intended only to refresh your memory rather than to be an authoritative, all
inclusive text. The overall objective of this subcourse is to introduce you
to the unique aspects of operation and maintenance peculiarities of the
Model 5345A.
The extent to which this purpose is achieved rests entirely
with you.
This subcourse is organized as follows:
Lesson 1 Electronic Counter Fundamentals
2 hours
Lesson 2 Model 5345A Operation
2 hours
Lesson 3 Model 5345A Theory of Operation
3 hours
Lesson 4 Model 5257A Transfer Oscillator
3 hours
Lesson 5 Model 5261A Video Amplifier
2 hours
