Subject: [TN] Controlled Impedance measurements

Technetters, I am trying to measure the impedance of some traces on a printed circuit board, traces that are 2.5 cm - 3.5 cm in length. They are too short for the TDR here to measure. Could a Vector Network Analyzer make impedance measurements on traces that short? If so, does anyone know of a lab that could make such measurements?
