MOHR Test and Measurement

MOHR Test and Measurement LLC, also known as Mohr and Associates, designs and manufactures portable time domain reflectometers (TDRs) and other sensor instruments. The company was founded in 1983 in Richland, Washington, with financial support from the US Nuclear Regulatory Commission to continue work on reactor safety instrumentation after loss-of-coolant experiments at the NRU facility. It later developed Electric Field Perturbation (EFP) ultra-wideband guided radar technology and has provided sensor technology and engineering consulting for more than 40 years. MOHR holds ISO 9001:2015 certification.

CT100 series TDR cable analysers

The CT100 family was developed as a portable high-resolution TDR for cable and wire testing and is used by US national laboratories and aerospace and defence companies. The current CT100B is described as the industry's highest-resolution portable metallic TDR and the only one with frequency-domain tools including return loss (S11), cable loss (S21) and Smith charts. Specifications include a 20 to 80 percent rise time under 100 ps (under 80 ps on the CT100HF), a 500 Hz frame rate for catching transient faults, 0.76 ps cursor resolution (about 25 micrometres), a bright colour screen, long battery life, more than 2 GB of storage, USB and Ethernet connectivity and support for keyboards, thumb drives and barcode readers. MOHR states that it exceeds all TDR specifications of the Tektronix 1502, 1502B and 1502C. The CT100B was released in 2016 after the CT100HF.
