Abstract: A measurement instrument configured to perform an associated method separates two signals which are present on the same signal line at the same time (e.g., an incident signal and a reflected signal) so that it can measure each signal by itself. In an example, the method may include: receiving a first probed waveform from a first location on a signal line between a source device and a destination device while an output of the source device sends an incident signal to an input of the destination device via the signal line; receiving a second probed waveform from a second location on the signal line, while the output of the source device sends the incident signal to the input of the destination device via the signal line; and ascertaining from the first probed waveform and the second probed waveform the reflection coefficient at the input of the destination device.
