26 Keysight E4412A and E4413A Operating and Service Guide
Power meter calibrations
Follow the calibration procedures given in your power meter manual. The E4413A
power sensor is fitted with 3.5 mm (m) connectors as standard. To convert the 3.5
mm (m) connector for calibration, an adapter (3.5 mm (f) to Type-N (m)) is
included with the power sensor. See Figure 1-3.

E4413A power sensor with adapter
– The 3.5 mm to Type-N adapter is intended for the use of the 1 mW, 50 MHz
power reference of the power meter only. Its function as a calibration
reference may be compromised if it is used for other purpose.
– The adapter supplied with a new sensor typically has a loss of < 0.1%.
Adapter loss could potentially contribute to absolute power measurement
accuracy and needs to be considered.
