Measurement failures can be divided into two categories:

• Failures which don't affect the normal functioning of the analyzer but render incorrect

measurement data.

• Failures which impede the normal functioning of the analyzer or prohibit the use of a

feature.

This chapter addresses the first category of failures which are usually caused by the

following:

• operator errors

• faulty calibration devices or connectors

• bad cables or adapters

• improper calibration techniques

• RF cabling problems within the test set.

These failures are checked using the following procedures:

• “Inspect the Accessories” on page 9-4

• “Inspect the Error Terms” on page 9-5

• “Test Set Troubleshooting” on page 9-8
