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