Introduction

The test methodology and equipment described herein can be used to gain some confidence in the 

measurement accuracy of the MA24106A Power Sensor. This is accomplished by comparing the sensor to 

another sensor with a specified cal factor and linearity performance or uncertainty. General commercially 

available equipment is used for these tests; however, these procedures are not sufficiently accurate to verify 

sensors to factory specification. Therefore, sensor test limits in these procedures are set appropriately to the 

specified comparison equipment. All tests should be performed at an ambient temperature of 20ºC to 25ºC.

Refer to the following sections for required equipment and test procedures:

• Required Equipment

• VSWR Pretest

• Calibration Factor Test

• Linearity Test

Required Equipment

Note:  Calibration and verification of high accuracy Power sensors requires substantial investment in both skill

and equipment. For calibration, calibration verification, and to maintain the factory specifications of your

power sensor, please send sensors to qualified Anritsu Customer Service Centers.
