S

STABILITY

In a magnetron, the ability to maintain normal operating characteristics [18].

STAGE

One of a series of circuits within a single device; for example, first stage of amplification [8].

STAGGER TUNING

A method of klystron tuning in which the resonant cavities are tuned to slightly
different frequencies to increase the bandwidth of the amplifier [11].


STANDING WAVE

The distribution of voltage and current, formed by the incident and reflected waves, that has minimum and maximum points on a resultant wave that appear to stand still [10].


START

The first unit of a teletypewriter signal. It is always a space [17].

STATIC

(1) A fixed nonvarying condition, without motion [13]. (2) Atmospheric noise, as in a receiver.

STATIC ELECTRICITY

Stationary electricity that is in the form of a charge. The accumulated electric
charge on an object [1].


STATOR

(1) The stationary part of a rotating electrical machine. The stator may be either the field or the armature, depending on the design of the machine [5]. (2) The stationary member of a synchro that consists of a cylindrical structure of slotted laminations on which three Y-connected coils are wound with their axes 120 degrees apart. Depending on the type of synchro, the stator's functions are similar to the primary or secondary windings of a transformer [15].


STATUTE MILE

5,280 feet [18].

STEP-BY-STEP COUNTER

A counter that provides an output for each cycle of the input in one-step
increments [9].
