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.
Procedure
First zero and calibrate the power meter/sensor combination.
1
Ensure the power sensor is disconnected from any signal source.
2
Press

E9300A
E9300H
E9301A
E9301H
E9304A
These power sensors connect directly to the POWER REF.
E9300B
E9301B
These power sensors are configured with an attenuator. Prior to calibration this
attenuator must be removed. Replace the attenuator before making measurements.
