Measurement Uncertainty

When calculating measurement uncertainty the significant multimeter
uncertainty parameters are for V
which should be included are:
Maths Assumptions: ± 0.01%
•
Effective Efficiency Calibration: ± 0.05%
•
Mismatch Uncertainty with Source and Mount: ± 0.1%
•
SWR: ≤1.05
•
These values are typical.
