Purpose and Function

These Coaxial RF Power Standards are designed for the precise measurement of microwave power in the
10 MHz to 50 GHz frequency range. These standards can be configured as a Reference Standard or
Working Standard. The Working RF Power S ta ndard (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 ter m inat ing t hermistor 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 sen sors.

Section I – Introduction

Preparation For Calibration Or Repair Service

Once you have verified t hat 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
States Only).

The RMA number is unique to your instrument and will help us identify you inst rument and to addre ss 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 inform ation such as measure ment 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 w il l assist them in identifying and correcting the problem in the
quickest possible manner. Use a copy of the Repair a nd C alibration 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.
