Time Domain Reflectometer (TDR) Cable Tester - MOHR CT100

Industry's Highest Resolution Portable Time-Domain Reflectometers



CT100B with a self-grounding BNC test port

  • Electrically-rugged, multipurpose metallic TDR designed for high-resolution testing of a wide range of coaxial and twisted-pair cable types and lengths -- in the field, on the manufacturing floor, or in the lab. Exceeds all Tektronix® 1502C TDR specifications.

CT100HF with a stainless-steel SMA test port

  • Higher-bandwidth version of the CT100 featuring the fastest TDR system risetime, ideal for testing high-frequency cables and interconnects with resolution and precision previously restricted to unwieldly bench-top TDR instruments.



Key TDR Specifications

  • The only portable TDR able to resolve connector detail (<1 cm)
     (At least 8-10x sharper spatial resolution than competing TDR instruments; catch subtle changes before they cause system failure)
  • Much faster and easier to use than VNA, similar broadband fault sensitivity with orders-of-magnitude better distance-to-fault precision and accuracy
     (NO range/resolution/bandwidth tradeoffs, NO calibration drift)
  • Industry's most accurate impedance measurements
     (16-bit ADC, advanced calibration features)
  • Industry's most accurate cable length measurements
     (80 μm [760 fs] cursor resolution, 6-digit VoP)
  • Industry's fastest intermittent fault detection
     (250 KSPS, 500 Hz continuous full waveform capture)
  • Industry's only portable TDR exceeding all Tektronix® 1502C TDR specifications


Applications

  • Tests all coaxial, twisted-pair, and multi-conductor (e.g. MIL-STD-1553B, MIL-STD-38999) cable types.
  • Detects subtle partial faults, opens, shorts, kinks, taps, shield damage, thermal damage, sunlight/UV damage, water ingress, loosened or corroded interconnects, poor-quality cables and connectors.
  • CATV, Power, Telephony
  • Naval / Marine
  • Aerospace / Aviation
  • Wireless Infrastructure
  • PCB Characterization
  • TDR Sensor Applications (Soil Moisture, Geophysics)
  • Remote monitoring applications

The Mohr CT100/CT100B was chosen as the replacement for the Tektronix 1502/1502B/1502C by the U.S. Navy.

The CT100 series are the only portable TDR cable testers exceeding all of the Tektronix® 1502/1502B/1502C TDR specifications. See comparison.
 



Key Software features -- see CT100 Series Features

  • Two independent cursors simplify differential impedance, return loss, and distance-to-fault measurements.
  • Save thousands of TDR traces that you can later zoom in/out on, and compare or subtract from live or previously saved traces.
  • Live LAN/WAN/Internet streaming and remote control of any CT100 Series TDR. Leverage real-time engineering oversight from thousands of miles away.
  • Download your TDR data to a PC and review it later with the included CT Viewer software.
  • Layer-Peeling reduces TDR waveform impedance errors caused by multiple reflections.
  • Transform impedance waveform to display in Ohms or VSWR as well as millirho.
  • Intermittent Fault Detection displays probability density or min/max envelope with impedance-at-cursor.
