Functional Test Procedures Functional Test Procedures There are three procedures in this section that provide a quick way to confirm basic functionality and proper adjustment of the DSA8300: (See page 2, Instrument Diagnostics.) (See page 3, Instrument and Module Compensation.) (See page 6, Instrument Functional Tests.)
Performing a vertical compensation will maximize the accuracy of the automatic measurements you take. This procedure uses internal routines to optimize the vertical offset, gain, and linearity. A complete compensation requires running separate compensations on the mainframe and the modules. DSA8300 Performance Verification...
