Note: The specifications for the Model 8203 ap-

ply only as long as the ambient temperature

remains at 30°C (+86°F) or lower.

Dimensions

and Weight

The Models 8201 and 8203 are 16-13/16 inches L x 5-15/16

inches W x 8-1/2 inches H (427 x 151 x 216 mm). They have

a net weight of 20.4 lb (9.2 kg) and a shipping weight of ap-

proximately 26 lb (12 kg).

Power and

Utility

Requirements

As load resistors, the Models 8201 and 8203 are passive de-

vices that are self contained and do not require a source of

power or utility service to perform their function, other than

the RF input power.

Environmenta

l

Requirements

The load should be operated in an environment as free of

dust and vibration as possible. For proper operation the am-

bient temperature should remain within the range of -40°C

to +45°C (-40°F to +113°F) for Model 8201 and -40°C to

+30°C (-40°F to +86°F) for Model 8203. Allow at least six

inches of clear space around the load to provide an unim-

peded flow of convection air currents for adequate heat dis-

sipation.

Items

Supplied

The load is equipped with:

s

Model 8201 — Female N connector of a pat-

ented “Quick-Change” design.

s

Instruction Manual.

s

Model 8203 — Double Male N adapter, and a

connector dust cap.

s

Instruction Manual.

Because these load resistors are self contained, they have no

additional parts.

Items

Required

Only a coaxial cable with the appropriate connector plug

(normally a Male N or, with the Model 8203, a Female N), is

needed for connecting these load resistors to the source of

RF power.

Tools and

Test

Equipment

s

Screwdrivers — for disassembly of this equip-

ment.

s

An ohmmeter with an accuracy of 1 percent or

better at 50 ohms is recommended for check-

ing the resistance value of the resistor.
