c. Supported PSG models:
E8244A
E8247C
E8254A
E8257C
E8257D
E8267C
E8267D
Note: One PSG with Option 567, 1EA, 1E1, 007, and UNX or UNR can be used as the Microwave Signal
Generator #1, Low Noise Signal Generator, and the RF Signal Generator.
d. 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 calibra-
tion 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.
e. When ordering a new STD or CFT Power Sensor from Keysight to be used with the N7800A series
applications, order with Option 1A7. The 1A7 option provides an ISO17025 calibration and includes
calibration data. When re-calibrating your STD or CFT Power Sensor for use with the N7800A series
applications, we recommend the Keysight ISO17025 calibration.
f. The step attenuators should be permanently joined via the 11716A Interconnect Kit as shown in the
following diagram.
For more information on step attenuator characterization, see the “Step Attenuator Loss Character-
ization” section below.
