Appendix B Verification and Calibration
130 Series N6700 User’s Guide
Verification
Verification procedures perform two primary functions:
Performance
Tests
These tests verify that the power system is operating normally and meets the
specifications published in Appendix A.
Calibration Tests These tests verify that the power system is operating within its calibration
limits.
If the power system fails any of the tests or if abnormal test results
are obtained, try calibrating the unit. If calibration is unsuccessful,
return the unit to an Agilent Technologies repair facility (see
Appendix D).
Equipment Required
The equipment listed in the following table, or the equivalent to this
equipment, is required for the calibration and performance tests. A
test record sheet may be found at the back of this section.
