Installation Note E8251-90382 5Add Option 1EH (Improved Low Band Harmonics from 10 MHz to 3.2 GHz) Kit Part Number:E8251-60382Safety ConsiderationsCheck Signal Generator FunctionalityUse the following procedure to confirm that the signal generator powers up and the internal checkidentifies no errors. The internal check evaluates the operation of the signal generator and returnsan error message if it detects a problem.1. Turn on the signal generator and let it warm up for at least five minutes.2. Run the signal generator self-test by pressing Utility > Instrument Info/Help Mode > Sel fTest > Run Complete Sel f Test. Upon completion, a summary of the self-test will bedisplayed.
