3 Using E9300 E-Series Power Sensors

Introduction

The E9300 E-Series power sensors are true average, wide dynamic range RF
microwave power sensors. They are based on a dual sensor
diode pair/attenuator/diode pair. This technique ensures the diodes in the
selected signal path are kept in their square law region, thus the output current
(and voltage) is proportional to the input power. The diode pair/attenuator/diode
pair assembly can yield the average of complex modulation formats across a wide
dynamic range, irrespective of signal bandwidth. Further refinements are included
to improve power handling allowing accurate measurement of high level signals
with high crest factors without incurring damage to the sensor.
These sensors measure average RF power on a wide variety of modulated signals
and are independent of the modulation bandwidth. They are ideally suited to the
average power measurement of multi-tone and spread spectrum signals such as
CDMA, W-CDMA and digital television formats.
Please refer to the documentation supplied with your E-Series E9300 power
sensor for specification and calibration information.
