Inv Source Impulse Response (Channel Quality)

Inv Source Impulse Response (Balanced) is the inverse stimulus source impulse response that is due to reflections/multipath. 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 Ch Impulse Response trace description for more information.

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

I and Q Source Impulse Response Traces

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