Attenuator Slope Check Preamp On Utility

This utility applies to the following models:

The Attenuator Slope Check Preamp On Utility can be used to check for damaged or broken RF attenuators. The utility measures amplitude relative to the 10 dB for attenuator settings of 0, 2, 4, 6, and 8 dB at several frequencies across the DUT tuning range. The relative amplitude measurements are then written to a text file for review. If amplitude error is large for a certain attenuator step, then the DUT may have a broken RF attenuator.
