1 mW Power Reference Level Test

Description

This test uses an 8482A power sensor to transfer the power measured on an
accurately calibrated power meter to the DUT as reference.

Required test equipment

– 1 unit of reference power meter (E4416A, E4417A, N1911A, N1912A, or
– 1 unit of power sensor (8482A or equivalent)

Test method

1 Obtain the 1 mW power level of the reference power meter from the calibration
The 1 mW reference of the power meter used must be precisely calibrated at a
