Chapter 5 — Sensor Operational Tests

5-1 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.

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.

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

•Required Equipment

•VSWR Pretest

•Calibration Factor Test

•Linearity Test
