Measurement Uncertainty

The following table lists the measurement uncertainty and ratio for each performance test using the recommended test equipment. Except for the External Trigger test, the ratios listed for the recommended test equipment meet or exceed the measurement uncertainty ratio required by U.S. MIL-STD-45662A.

•If you are using equipment other than the recommended test equipment, you may calculate and record the measurement uncertainty and ratio for each performance test. The table may be reproduced without written permission of Agilent Technologies.
