Your New Choice for Accurate Power
Measurements from 50 to 75 GHz
Compatible with Your Current Agilent
Power Meter
The Agilent Technologies V8486A V-band power
sensor is fully compatible with Agilent 435B, 436A,
437B, 438A, 70100A, E1416A, E4418A/B, and
E4419A/B 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, the V8486A
offers a specified SWR of 1.06 (>30 dB return loss).

50 MHz Calibration
For easy calibration with the power meter, the
Agilent V8486A incorporates 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
The V8486A uses the same proven Modified
Barrier Integrated Diode (MBID) technology found
in other Agilent sensors, and always operates in
the square-law characteristic for true-average detection.
The uncertainty analysis for the calibration of the V8486A is carried out in accordance with the ISO/TAG4 Guide. The uncertainty
data, reported on the calibration certificate, is the expanded
uncertainty with a 95% confidence level and a coverage factor
(k) of 2.
