The E8486A from Keysight is a Power Sensor that operates from 60 to 90 GHz. The power sensor provides an excellent SWR of 1.06, high reliability, low loss (> 30 dB return loss), and has a 50 MHz calibration port to reduce measurement uncertainties. It has a dynamic range spanning from -60 to +20 dBm. This device can handle a maximum average power of up to 200mW and peak power of up to 40 W. It is available in a module with WR-12 Waveguide and UG-387/U Flange.
Keysight waveguide power sensors are fully compatible with Keysight EPM (E4418B/19B, N1913A/14A), EPM-P (E4416A/17A) and P-Series (N1911A/12A) power meters.
