The handheld Time Domain Reflectometer (TDR) consists of CM Technologies’ PCI-3127 high-performance metallic TDR card packaged in a rugged handheld computer form factor. The software interface uses an easy to follow menu structure to assist in acquiring, saving and interpreting TDR signatures – extremely flexible when compared to traditional instrumentation.
Current for 2014: Model PCI-3160R (PDF Spec Sheet)
Our latest handheld PCI-3170R TDR is a psuedo real-time replacement for the Tektronix® 1502C and 1503C TDR instruments.
Scheduled for 2015: Model PCI-3170R (PDF Spec Sheet)
