Termaline Coaxial Load Resistor.

This chapter contains introductory information including

product specifications, items supplied, and accessory items

available.

Purpose and

Function

The Series 8000 Termaline Load Resistors are portable,

general purpose 50 ohm coaxial transmission line termina-

tions. They are self-contained units, liquid free and air

cooled, requiring no outside power source or additional

equipment. They provide accurate, dependable, and practi-

cally nonreflective terminations for testing and adjusting

transmitters under nonradiating conditions. These loads are

useful for the following purposes:

As a substitute antenna.

For tuning RF transmitters under

nonradiating conditions.

For making routine tests and adjustments.

As a substitute for any circuit loading ele-

ment.

To measure, with a suitable indicating device,

the power output of any coaxially transmitted

RF signal within their rating.

Performance

Characteristics

and

Capabilities

Series 8000 dry loads can absorb their individual maximum

rated RF power levels continuously and dissipate them

harmlessly as heat over their entire frequency range. Be-

cause they are dry, they are attitude insensitive and can

therefore, with some restrictions, be used in any position.

Consult the Specification Sheet, Page 3, for a listing of their

individual power ratings, frequency ranges, and VSWR val-

ues.

Dimensions

and Weight

Consult the Specifications on Page 3 for the size and weight

of each load.
