5 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.
