Inv Source Frequency Response (Channel Quality)

Inv Source Frequency Response (Balanced) is the balanced part of the inverse stimulus source frequency response. The Stimulus Source traces are good for troubleshooting (if your DUT Device under Test: An acronym used to describe some type of electrical apparatus connected to test instrumentation. The apparatus can range from a single component to a complex subsystem such as a mobile phone, base station or MSC. response traces look bad, check the Stimulus Source traces to see if the stimulus looks as expected). See the Inv Source Frequency Response trace description for more information.

The non-averaged inverse stimulus source frequency response is shown in the Inst Inv Source Frequency Response trace.

I and Q Inv Source Frequency Response Traces

There are also traces for I and Q that express the inverse frequency response separately for the In Phase and Quadrature Phase components of the stimulus source. These traces are computed from the Balanced and Unbalanced responses.
