Time Domain Transmission (TDT)

All probes have a loading effect on the circuit when they
come in contact with the circuit. Time domain transmission
(TDT) measurements are useful for understanding the probe
loading effects as seen at the target receiver. The following
TDT measurements were made mid- bus on a 50Ω
transmission line load terminated at the receiver. These
measurements show how the soft touch probes affect an
ideal step seen by the receiver for various rise times.

The following plots were made on an Agilent 54750A
oscilloscope using TDT.
