Recommended verification equipment
The following table summarizes recommended maximum allowable test equipment uncertainty for
verification points. Total test equipment measurement uncertainty should meet or be less than the
listed values at each test point. Generally, test equipment uncertainty should be at least four times
better than corresponding Series 2600B specifications.
