Chapter 4 Calibration Procedures
AC Amplitude Verification
Install the 50W feedthrough load between the DMM and the function generator output. Set the function generator for each output indicated in the table on the next page. Use a DMM to measure the ACrms output voltage of the function generator. Compare the measured results to the test limits shown in the table. This is a 50W output termination test.
