This module uses two analog RF sources combined after an upconverter through waveguide “magic tee” and a downconverter to analyze IMD with a Spectrum Analyzer. In this case, two upconverters and two step-attenuators are used to control f1 and f2 independently.


Scalar waveguide setup for 2-Tones Measurements (IQS200B-20) using two independent LO sources for Up & Down converters.
