52 Keysight N1913/1914A 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 N8482A sensor, measure
the 1 mW power reference of the E4419B or E4417A.
3 Using the E4419B or E4417A power meter and the N8482A sensor, measure
the 1 mW power reference of the DUT.
4 Using all of these values, the N7800 Series 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" ).
