20 Keysight E4412A and E4413A Operating and Service Guide
Description
The E4412A and E4413A power sensors are diode power sensors. They are
intended for measurement of CW microwave power levels in a wide dynamic
range from -70 dBm to +20 dBm (100 pW to 100 mW). The E4412A measures at
frequencies from 10 MHz to 18.0 GHz. The E4413A measures at frequencies from
50 MHz to 26.5 GHz. These are high-speed power sensors, and do not incorporate
narrow-bandwidth averaging used in average-power sensors. Signals with digital,
pulse, or other forms of amplitude modulation may introduce measurement errors.
Multi-tone signals (containing multiple frequency components), or signals with
significant harmonic content (> -45 dBc) may introduce measurement errors at
high power levels. (Specifications for the power sensors are in the datasheet).
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.
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.
