The CT100 Series Automated Metallic TDR Cable Tester family was developed in response to an industry need for a portable high-resolution TDR instrument optimized for cable and wire testing. The CT100 TDR is in use by multiple U.S. national labs, numerous aerospace and defense technology companies, and has been selected by the U.S. Navy for its General Purpose Electronic Test Equipment (GPETE) program. The CT100 was designed to support a variety of Navy and Marine Corps applications, replacing the discontinued Tektronix(R) 1502B/C TDRs.

Development of the MOHR TDRs has continued, first with the release of the more advanced CT100HF and then in 2016 the release of the CT100B. MOHR continues to improve the world’s finest portable TDRs.
