Measurement Accuracy
Power sensors have small errors in their response over frequency. The response of
each sensor is measured during manufacture to determine correction factors.
With E-Series power sensors, correction factors are held in Electrically Erasable
Programmable Read Only Memory (EEPROM) and are downloaded to the power
meter automatically.
Using calibration factors enables improved measurement accuracy. This section
describes making average power measurements using the E9300 E-Series power
sensors.
Making a measurement requires the following steps:
1 Zero and calibrate the power meter/sensor combination.
2 Set the frequency for the signal you want to measure.
3 Make the measurement.

E9300A
These power sensors connect directly to the POWER REF.
E9300H
E9301A
E9301H
E9304A
E9300B
These power sensors are configured with an attenuator. Prior to calibration this attenuator must be
