TDR Cable Tester (Time-Domain Reflectometer)

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 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.)
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.

Key Software features

Two independent cursors simplify differential impedance, return loss, and distance-to-fault 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. See comparison.

Designed to be easy to use, as well as accurate

Bright 4.3" color TFT-LCD display is easy to read in any environment.
