20 Keysight E4412A and E4413A Operating and Service Guide
These power sensors measure CW power, displayed on a compatible power meter
in logarithmic (dBm or dB) or linear (Watts or %) measurement units. The E4413A
is shipped with a 3.5-mm to Type-N adapter, part number 08485-60005.
Specifications
For the specifications of the E4412A and E4413A power sensors, refer to the
datasheet at http://literature.cdn.keysight.com/litweb/pdf/5990-4019EN.pdf.

sensor at 25 ºC (typical)
The E4412A and E4413A power sensors are compatible ONLY with the newer
E44XX-Series power meters. They are NOT compatible with the earlier
430-Series, E1416A, or 70100A power meters.
The E4412A and E4413A power sensors are extremely static- sensitive. Do not
open the power sensor unless you and the power sensor are at a static-free
workstation.
