Keysight 3458A - Introduction to Operating Information

2 Operational Verification Tests
28 Keysight 3458A Calibration Manual
Introduction
This section contains Operational Verification Tests which provide an abbreviated
method of testing the operation and accuracy of the unit. The Operational
Verification Tests are designed to provide a 90% confidence that the 3458A is
operational and meets the specifications listed in Appendix A.
Operational Verification Tests perform a three point verification. These three
points are the basis for all internal electronic adjustments (see the section titled
The basis for auto-calibration in Appendix B, "Electronic Calibration of the 3458A
(Product Note 3458A-3)"). Prior to the three point test, a self test verifies that all
calibration constants are within their upper and lower limits, an indicator of proper
operation.
