1 Measurement uncertainty ≤1.9%. At room temperature and excluding power level dependent
terms (zero set, drift, and noise). Refer to Keysight Fundamentals of RF and Microwave Power
Measurements (Part 3) Power Measurement Uncertainty per International Guide (Application
Note 1449-3), 5988-9215EN for more information on measurement uncertainty.
