Keysight N1911A/1912A 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.
