Electrical Safety Precautions



Any s

ervicing inst

ructions are for use by service

-

trained personnel only. To avoid personal injury, do not

perform any service unless

you are

qualified to do so.



For continued protection against fire hazard, replace the

AC line fuse only with a

fuse of the same current

rating and type. Do not use repaired fuses or short circuited fuse holders.

1.5

Important Operating Instructions



The GT

-

1020A

Amplifier does not include

an enable/disable feature to activate and deactivate the amplifier.

When connecting or disconnecting the output of the amplifier, ensure that the power switch

on the rear

of

the amplifier is in the OFF position.



When connecting the amplifier to a transmit

ting device, observe all safety procedures to ensure that the

amplifier isn’t interfering with other systems in the area. High power microwaves can adversely affect power

sensitive instruments in the area of transmission.



Exercise precautions to avoid expo

sure to radiated microwave energy at all times.

provide excellent pulse fidelity, low intermodulation distortion, high

linearity and superior gain flatness without the warm

up time, drift or aging issues of traveling wave tube

amplifiers

(TWTA). They feature low noise figure, low harmonics and spurious content, and are highly tolerant to

load mismatch.
