Chapter 3 Operation

3.1 Operating Safety and Instructions

DO NOT EXCEED AN INPUT LEVEL OF +20 dBm INTO THE GT-1020A. EXCEEDING

THIS LEVEL CAN DAMAGE THE GT-1020A MICROWAVE POWER AMPLIFIER.

WHEN ENERGIZED, THE GT-1020A IS CAPABLE OF SUPPLYING POWER THAT

CAN CAUSE DAMAGE OR INJURY. TAKE THE FOLLOWING PRECAUTIONS TO

ENSURE SAFE SETUP AND OPERATION:

Verify that all cables, connectors, and equipment connected to the

GT-1020A are in good condition.

Do not make connections to equipment while the output of any item of

equipment is energized.

Table 4: Operate the GT-1020A

Step

Action

1.

Verify that the POWER switch on the rear of the unit is OFF.

Plug the included AC line cord into a source of AC power that meets the specifications for

power in Table 10 on page 13.

Put the POWER switch on the GT-1020A in the ON position.

NOTE:

For best results, let the GT-1020A warm up for one minute after switching the AC power

ON.

2.

Verify that the output of the microwave signal source is

NOT

energized before continuing to the

next step.

3.

Connect the equipment to the GT-1020A according to your application.

NOTE:

Verify all mating connectors are 50 Ohm, and that they are in good condition.

4.

Energize the output of the microwave signal source.

5.

Adjust the output of the microwave signal source until the output from the GT-1020A is at the

desired level.

End of Procedure
