E Series Wide Dynamic Range Power Sensor, CW Only (10 MHz to 18 GHz)
The E4412A and E4413A power sensors are diode power sensors. They are intended for the 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 a 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.
