A.H. Systems Model PAM-1840 Pre-Amplifier

INTRODUCTION

BEFORE APPLYING POWER

Review this manual and become familiar with all safety markings and instructions.

Verify that the equipment line voltage is compatible with the main power source.

INTENDED PURPOSES

This equipment is intended for general laboratory use in a wide variety of industrial and

scientific applications, and designed to be used in the process of generating, controlling

and measuring high levels of electromagnetic Radio Frequency (RF) energy. Therefore

the output of the amplifier must be connected to an appropriate load such as an

antenna, field-generating device, or receiver. It is the responsibility of the user to assure

that the device is operated in a location which will control the radiated energy such that

it will not cause injury and will not violate regulatory levels of electromagnetic

interference.

HAZARDOUS RF VOLTAGES

The RF voltages on the center pin of the RF output connector can be hazardous. The

RF output connector should be connected to a load before AC power is applied to the

amplifier.

RANGE OF ENVIRONMENTAL CONDITIONS

This equipment is designed to be safe under the following environmental conditions:

While the equipment will not cause hazardous condition over this environmental range,

performance may vary.
