Waveguide Power Sensors
Make accurate and reliable measurements in the 50 to 110 GHz frequency range with Keysight’s family of waveguide power sensors
Covering the V-band, E-band and W-band spectrums, the Keysight Technologies, Inc. waveguide power sensors offer best SWR, high reliability and low loss, and come with a 50 MHz calibration port to reduce measurement uncertainties. And with the Keysight E8486A (Option 200) waveguide sensor, you also get a wide dynamic range spanning from -60 to +20 dBm.
Compatible with your current Keysight power meter
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. The V8486A and W8486A are also compatible with the discontinued or obsolete power meters such as 435B, 436A, 437B, 438A, 70100A, E1416A, E4418A, and E4419A power meters.
Best SWR available
In RF and microwave power measurements, the largest single source of error is usually sensor and source mismatch. To minimize any measurement uncertainty caused by mismatch, Keysight waveguide sensors offer excellent SWR of 1.06 (> 30 dB return loss).
50 MHz calibration
For easy calibration with the power meter, Keysight waveguide power sensors incorporate a 50 MHz calibration port. This eliminates the variance in making measurements with different meter/sensor combinations and the uncertainties due to temperature changes. It also provides traceability to the U.S National Institute of Standards and Technology (NIST) at millimeter-wave frequencies.
High reliability
Keysight waveguide sensors use the same proven Modified Barrier Integrated Diode (MBID) technology found in other Keysight sensors, and always operates in the square-law characteristic for true-average detection.

E8486A E-Band Waveguide Power Sensor
Meet the rapid demand in E-band telecommunication applications with the E8486A waveguide power sensor. Designed with a WR-12 flange connector, the E8486A makes precise and direct waveguide measurements in the E-band frequency range and is compatible with most Keysight power meters. A wide dynamic range of -60 to +20 dBm and a SWR performance of 1.06 minimize measurement uncertainty caused by mismatch, providing high accuracy even with low power signals. With the E8486A waveguide power sensor, get the precision and accuracy you need for E-band applications in a single power sensor.
V8486A V-Band Waveguide Power Sensor
Make accurate average power measurements from 50 to 75 GHz with the V8486A V-band power sensor. A special option for the V8486A that extends the power range down to -60 dBm is available. Contact your local Keysight field engineer or sales office for more information.
W8486A W-Band Waveguide Power Sensor
The W8486A waveguide power sensor measures average power over the frequency range 75 to 110 GHz and power range –30 to +20 dBm.
Mechanical characteristic
Mechanical characteristics such as center conductor protrusion and pin depth are not performance specifications. They are, however, important supplemental characteristics related to electrical performance. At no time should the pin depth of the connector be protruding.
