Using E4410 E-Series Power Sensors 6
Keysight N1911A/1912A User’s Guide 205
Measurement Accuracy
Power sensors have small errors in their response over frequency. The response of
each sensor is measured during manufacture (and during periodic calibration).
With E-Series power sensors, the resulting frequency compensation information is
written into Electrically Eraseable Programmable Read Only Memory (EEPROM).
This allows the frequency and calibration data to be downloaded to the power
meter automatically.
Using calibration factors enables you to achieve improved measurement
accuracy. This section describes making continuous wave measurements using
the E4410 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 and the channel softkey. The Zeroing pop-up is
displayed.
3 Connect the power sensor to the POWER REF output.
4 Press and the channel softkey to start the calibration routine.
The Calibrating pop-up is then displayed.
