Section I – Introduction

Purpose and Function

These Coaxial RF Power Standards are designed for the precise measurement of microwave power in the

6 kHz to 18 GHz frequency range. These standards can be configured as a Reference Standard or Working

Standard. The Working RF Power Standard (or Feedthrough RF Power Standard) is a thermistor mount

with power splitter combination employed as a Feedthrough standard for the calibration of terminating

power sensors such as thermoelectric, diode and thermistor power sensors. The Reference RF Power

Standard (or Terminating RF Power Standard) is a terminating thermistor mount used for the calibration

of Feedthrough standards and applications that require direct measurement of RF power.

Capabilities

These Coaxial RF Power Standards are designed for the calibration laboratory. These units are highly

accurate, stable with time and temperature, and are designed for use as a standard for the

characterization of calibration factors for other sensors.

Section I – Introduction

Preparation For Calibration Or Repair Service

Once you have verified that the cause for the Coaxial RF Power Standards malfunction cannot be solved in

the field and the need for repair and calibration service arises, contact TEGAM customer service to obtain

an RMA, (Returned Material Authorization), number. You can contact TEGAM customer service via the

TEGAM website, www.tegam.com or by calling 440.466.6100 (All Locations) OR 800.666.1010 (United

States Only).

The RMA number is unique to your instrument and will help us identify you instrument and to address the

particular service request by you which is assigned to that RMA number.

Of even importance, a detailed written description of the problem should be attached to the instrument.

Many times repair turnaround is unnecessarily delayed due to a lack of repair instructions or of a detailed

description of the problem.

This description should include information such as measurement range, and other instrument settings,

type of components being tested, are the symptoms intermittent, conditions that may cause the

symptoms, has anything changed since the last time the instrument was used, etc. Any detailed

information provided to our technicians will assist them in identifying and correcting the problem in the

quickest possible manner. Use a copy of the Repair and Calibration Service form provided on the next

page.

Once this information is prepared and sent with the instrument to our service department, we will do our

part in making sure that you receive the best possible customer service and turnaround time possible.
