4. Attach the signal source to the Type N connector on the Model 3107B.
Use a voltage monitor or power monitor at the signal source to
determine the input voltage/power applied. The field strength capability
is shown in the tables on page 14 and page 16. A field intensity
monitor on the opposite side of the Model 3l07B from the test sample
and at the corresponding distance will give a good approximation of
the field seen by the sample.
