Waveguide W-Band Power Sensor (75 GHz to 110 GHz)
The W8486A waveguide power sensor measures average power over the frequency range 75 to 110 GHz and power range -30 to +20 dBm. Please note, the W8486A comes without built-in EEPROM. Users need to pre-enter calibration factors printed on the back of the sensor into the power meter.
Several versions available
Covering the V-band, E-band and W-band spectrums, Keysight 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.
| Model | Band | Frequency |
| V8486A | V band | 50 to 75 GHz |
| W8486A | W band | 75 to 110 GHz |
| E8486A | E band | 60 to 90 GHz |
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.
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.
