High Low Power Test

(N9912A)

This procedure first tests the maximum power output by the NA source at CW frequencies across the frequency range of the FieldFox. It then tests the linearity of the source step attenuator at 1 GHz. The reference receiver is used to measure the linearity. For each attenuator setting, the measured value is normalized to the power output level produced when the attenuator is set to zero dB. The measured error is calculated by subtracting the nominal attenuator setting from the absolute value of the measured value. The limits on the measured error are based on a population of attenuators with typical characteristics.

The following notes apply to illustrations in the FieldFox Help:

  • Only a single representative model will be shown.
  • Some illustrations may differ than those in TME.

  • For procedures that apply to multiple ports, illustrations will show the setup on only one test port.
