24 N1911A/1912A P-Series Power Meters Service Guide
Test Method
1 Enter the recorded measurement uncertainty of the E4419B or E4417A
1 mW power reference
2 Using the E4419B or E4417A power meter and the 8482A sensor,
measure the 1mW power reference of the E4419B or E4417A
3 Using the E4419B or E4417A power meter and the 8482A sensor,
measure the 1 mW power reference of the DUT
4 Using all of these values, the N7832A software will calculate the power
reference level of the DUT
NOTE
• The 1 mW reference of the E4419B or E4417A power meter must be precisely calibrated
at a standards accredited lab, and the uncertainty of this measurement known.
• Anyone who has a basic understanding of metrology should be able to perform this test
manually; it is simply the transfer of known power level with a known calibration
uncertainty to the DUT.
• An adjustment is available for this test if it fails (see Chapter 3, “Adjustments”).
