Measurement Uncertainty Analysis - Instrument Accuracy Test D
E4416A/E4417A Power Meters Service Guide D-155
Worst case error on 1V range
Error = ((8 ppm × 1.0 V) + (0.3 ppm × 1.0 V)) + (1 ppm × 1.0 V) + 5((0.15 ppm
× 1.0 V) + (0.1 ppm × 1.0 V))
= 10.55 μV
Percentage Error = 0.001055%
Worst case error on 10 V range
Error = ((8 ppm × 10.0 V) + (0.05 ppm × 10.0 V)) + (1 ppm × 10.0V) + 5((0.15
ppm × 10.0 V) + (0.01 ppm × 10.0 V))
= 98.5 μV
Percentage Error = 0.000985%
