5 Using E9300 E-Series Power Sensors
152 N1911A/1912A P-Series Power Meters User’s Guide
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.
