Abstract
A method of trace delay error compensation for measurements that are taken remotely from the signal source or receiver of a circuit uses data available from a computer aided design (CAD) tool to characterize electrical connections to an instrument measurement point, such as a connectorless probe, which is remote from the signal source or receiver. Extracted parameters from the CAD data are applied to signals acquired by the probe to adjust the signal timing and/or shape to more accurately represent the signal information timing at the signal source or receiver or other remote location of interest to a user. The corrected signals at the desired location may be displayed by a measurement instrument.
