Measurement Accuracy; Procedure - Keysight N1911A User Manual

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.
