Source Impulse Response (Channel Quality)

Source Impulse Response (Balanced) is the stimulus source impulse response corresponding to the 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 Ch Impulse Response trace description for more information.

The non-averaged channel impulse response is shown in the Inst Source Impulse Response trace.

I and Q Source Impulse Response Traces

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