Industry's Highest Resolution Portable Time-Domain Reflectometers

Time Domain Reflectometer (TDR) Cable Tester - MOHR CT100

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.

CT100B with a stainless-steel SMA test port

• Improved data signal quality with slightly less electrical overstress protection than the standard CT100B.

CT100HF with a stainless-steel SMA test port

• Higher-bandwidth version of the CT100 featuring the fastest TDR system rise time, 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.)

High-Resolution TDR. The CT100B's high resolution shows connector details that lesser devices completely miss.

• Much faster and easier to use than a 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
  (25 μm [0.76 ps] cursor resolution)
• Industry's fastest intermittent fault detection
  (250,000 samples per second, 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, and poor-quality cables and connectors.
• CATV, Power, Telephony
• Naval / Marine
• Aerospace / Aviation
• Wireless Infrastructure
• PCB Impedance Measurements
• TDR Sensor Applications (Soil Moisture, Geophysics)
• Remote monitoring applications
• Tank Farms

Key Software features

• Two independent cursors simplify differential impedance, return loss, and distance-to-fault measurements.Dual Cursors Simplify Differential Measurements
  Dual-Cursors make comparisons simple. Note the 41.1 Ω difference between the reading of the nominal 50 Ω and 90 Ω cable segments.
• 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™ 2 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.
• Enhanced Calibration provides the industry's best impedance accuracy.
• FFT Math Package for estimating frequency-specific return loss/VSWR, insertion loss, cable loss, S11/S22 S-parameters.
• AutoFit™ button scales the display settings to fit the attached cable.
• Configuration library makes repeat measurements as easy as a press of a button.

The Mohr CT100/CT100B was chosen as the replacement for the Tektronix® 1502/1502B/1502C by the U.S. Navy. The CT100 series TDRs are the only portable TDR cable testers exceeding all of the Tektronix® 1502/1502B/1502C TDR specifications. 

Designed to be easy to use, as well as accurate

• Bright 4.3" colour TFT-LCD display is easy to read in any environment.
• Intuitive multifunction key panels simplify TDR use.
• Lightweight and portable, operates for a full shift without recharging.
• Integrated 10/100 Mb Ethernet connectivity.
• Available USB peripherals: mouse, keyboard, flash drive, barcode reader.
