Waveguide Power Sensors
Data Sheet
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, Keysight's 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 dBm 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 uncertain-
ties due to temperature changes. It also provides traceability to the U.S National Institute of Standards and Technol-
ogy (NIST) at millimeter-wave frequencies.
High Reliability
Keysight waveguide sensors use the same proven Modiied Barrier Integrated Diode (MBID) technology found in
other Keysight sensors, and always operates in the square-law characteristic for true-average detection.
