MOHR Ships 1000th CT100 TDR Cable Tester

Industry's only high-resolution portable TDRs are used in a wide range of industries.

MOHR Test and Measurement LLC (MOHR), a supplier of time-domain reflectometry (TDR) cable test equipment, announced that it recently shipped its 1000th CT100 Series TDR cable tester to a U.S. military customer. The CT100, CT100S, and CT100HF TDR cable testers are used across a wide range of industries including aerospace, defense, telecom, automotive, and electric power, for precision testing of twisted pair, coaxial, and multiconductor cables and connectors. Like high-end benchtop TDRs, the MOHR instruments utilize a fast rise-time step test signal, and are prized for their ability to detect and localize subtle cable and connector faults and accurately measure cable impedance. The instruments' precision length measurements are also useful for phase-matching microwave cables.

"Our customers use the CT100 to test and qualify almost every type of cable you can imagine -- from aircraft instrumentation cables to phased-array radar cables to automotive engine wiring harnesses. We even have customers using the CT100 in submersible vehicles to test sea-floor cabling," said Brandt Mohr, chief technologist. "These are the only field TDRs that give you sub-centimeter connector-level resolution along with advanced features such as 16-bit sampling, FFT and S-parameter tools, layer-peeling, transient fault capture, and easy integration into production-floor automated test setups." Mohr says the rugged TDR has also found its way into geotechnical fault monitoring, soil moisture sensing, and other scientific applications.

The CT100 instrument family was originally released in 2009, and has received continuous upgrades, improvements, and new software features that are available to owners of earlier units through the instruments' web update feature.

About CT100 Series TDRs and CT Viewer Software

CT100 Series TDRs feature step-rise test signal, 0.003 in. (75 micron) cursor resolution, system rise-times as low as 60 ps (20-80%, CT100HF), and horizontal range of up to 44,000 ft. (13.4 km). The instruments can capture transient faults and feature unique software tools simplifying cable troubleshooting and maintenance. CT100 Series TDRs weigh approximately 5 lbs. (2.3 kg) and feature bright color screens, USB and 10/100 Ethernet connectivity, and support for USB peripherals including keyboards, flash drives, and barcode readers.

CT100 Series TDRs come bundled with CT Viewer, full-featured TDR waveform analysis software designed for Microsoft(R) Windows(R). CT Viewer lets the operator analyze and compare stored TDR waveforms, capture real-time video from CT100 Series TDRs at up to 500 waveforms per second, and remotely control CT100 Series TDRs over a LAN/WAN or the Internet. The software uses Microsoft(R) SQL Server(R) for reliable data storage.
