Patent ID: 8659315

Claim:
A method for characterizing a device under test in a trace structure, the trace structure comprising: a probing structure; the device under test; and a termination structure; wherein the probing structure is connected to one side of the device under test and the termination structure is connected to the other side of the device under test, the method comprising the steps of: determining the s-parameters of the termination structure for a first mode at at least one frequency; determining the s-parameters of the trace structure for a second mode at a plurality of frequencies; calculating a time limited time-domain waveform in accordance with the s-parameters of the trace structure; determining a reflection coefficient at the least one frequency in accordance with the time limited time-domain waveform; and determining a loss characteristic of the device under test for a third mode at the at least one frequency in accordance with the reflection coefficient, the s-parameters of the termination structure, and the at least one frequency.
