MASTER OSCILLATOR

In a transmitter, the oscillator that establishes the carrier frequency of the
output [18].

MASTER OSCILLATOR POWER AMPLIFIER

A transmitter in which the oscillator is isolated from the antenna by a power amplifier [12].

MATRIX

In computers, a logic network in the form of an array of input leads and output leads with logic elements connected at some of their intersections [13].

MATTER

Any physical entity that possesses mass [1].

MAXIMUM USABLE FREQUENCY

Maximum frequency that can be used for communications between two locations for a given time of day and a given angle of incidence [10].

MEASURE

(METROLOGY AUTOMATED SYSTEM FOR UNIFORM RECALL AND REPORTING)—The Navy data processing system designed to provide a standardized system for the recall, scheduling, and documenting of test equipment into calibration facilities [16].

MECHANICAL SCANNING

The reflector, its feed source, or the entire antenna is moved in a desired
pattern [18].

MECHANICAL-ROTATION FREQUENCY

The speed in revolutions per minute of armatures in electric motors and engine-driven generators; blade speed in turbines [16].

MECHANIZATION

Using electric or electro-mechanical switches to represent logic circuits (AND, OR, NOT, NOR, NAND) [13].

MEDIUM

The vehicle through which a wave travels from one point to the next. Air, water, and wood are examples [10].
