MEASUREMENT IN QUESTION

￿Condition of the 373XXA.

￿Quality and condition of the interface connections and connec- tors.

￿Quality and condition of the calibration components, through-lines, adapters and fixtures.

￿Surrounding environmental conditions at the time of the mea- surement.

￿Selection and performance of the calibration for the DUT being measured.

Measurement When determining possible measurement problems, check the follow-

Conditions Check List ing items:

1. Check the DUT and the calibration conditions:

￿ ensure the Calibration Components Coefficients data has been installed into the system from the Calibration Kit in use.

￿ ensure the proper calibration was done for the device being measured:

￿ For high insertion loss device measurements the calibra- tion should include isolation, high number of averages, and lower IF Bandwidth settings during the calibration.

￿ For high return loss device measurements the calibra- tion should also include a sliding load calibration.

￿ Check DUT mating connector(s) condition and pin depth. ￿ Measure an alternate known good DUT, if possible.

￿ Check if the environment is stable enough for the accuracy re- quired for the DUT measurement.

￿ The system should not be subjected to variations in tem- perature.

￿ The system should not be placed in direct sun light or next to a changing cooling source, such as a fan or air conditioning unit.

2. Check the calibration using known good components from the cal- ibration kit. If measurements of these devices do not produce good results:

￿ Check through-cable stability including condition and pin depth. Replace with a known good cable, if necessary.

￿ Check condition and pin depth of calibration kit components. Replace with known good components, if necessary.

￿ Check condition and pin depth of test port connectors. Replace with known good ones if necessary.
