Which parameter can cause interference during the downstream sweep test if set excessively high?

In the context of a downstream sweep test, the sweep test pulse amplitude is a crucial parameter that influences how the test interacts with various components in the system. If the sweep pulse amplitude is set excessively high, it can lead to interference issues during the test.

When the amplitude is too high, it can create signals that saturate the receiving equipment or cause distortion, masking the desired response from the component being tested. This saturation can overwhelm the electronic components and lead to erroneous results, as the system may not be able to accurately interpret the reflections or transmissions of the signals.

For effective sweep testing, maintaining an appropriate sweep pulse amplitude is essential to ensure that the signals are distinguishable and that the test can accurately assess the performance of the system under evaluation. By keeping the amplitude within a recommended range, the reliability and accuracy of the downstream sweep test can be optimized.
