a. Keysight, Agilent, or Hewlett-Packard model numbers unless otherwise noted.
b. P = Performance Testing, T = Troubleshooting
c. Supported PSG models:
E8247C
E8257C
E8257C
E8267C
E8267D
One PSG with Option 567, 1EA/1EU, 1E1, 007, and UNX, UNR, or UNY can be used as the Microwave Sig-
nal Generator #1, Low Noise Signal Generator, and the RF Signal Generator
PSG Option 521 is not supported as an alternative model for the X-Series performance verification tests
due to its upper and lower frequency limits.

e. N1914A power meters with serial number prefix prior to MY53040007 require Service Note N1914A-07
which fixes a power supply ground loop. The ground loop injects noise into the measurement circuits
which can cause unstable measurements at low (-30 dBm) power levels
f. The 8482A power sensor uses cal factors to compensate the power sensor for frequency response
errors. Cal factors are stated in percentages. The 8482A factory cal factor uncertainty ranges from 2.2%
to 3.1%. The cal factor uncertainty can be reduced to < 1.0% by using metrology grade calibration
techniques. The power sensor cal factor uncertainty becomes one component of the Verification Test
uncertainty analysis. Lower cal factor uncertainties will translate to wider test margins.
