TF-DSQ Probe Calibration and Deskew Fixture

TF-DSQ-OM-E RevC

Despite differential probes measuring differentially, they can be used to measure common

mode signals. In this case, the V- tip is connected to ground, and the probe continues to

measure the difference between the tips. This is a useful configuration for identifying ground

problems.

The voltages in differential systems can be described by the following diagram and equations:
