Agilent Technologies 33120A, Service Manual

Page: 61 / 146

Install the 50
W
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 50
W
output termination test.
