High-Resolution TDR with Frequency-Domain Analysis!

High-Resolution TDR with Frequency-Domain Analysis!

CT100B TDR Cable Analyzer
The CT100B* TDR Cable Analyzer is the industry's highest-resolution portable TDR, ideal for precision testing of all types of coaxial, twisted-pair, and multiconductor cables and connectors. The CT100B is the only metallic cable TDR with frequency-domain analysis tools including Return Loss (S11), Cable Loss (S21), and Smith charts.
The CT100B is the only portable instrument exceeding all TDR performance specifications of the popular Tektronix® 1502, 1502B, and 1502C TDRs.

CT100B Features

  • Sampling resolution is independent of display resolution --> every cable fault is visible at every scale
  • Arbitrary length waveforms up to 1.5 million points
  • Two independent cursors simplify differential impedance, return loss, and distance-to-fault measurements.
  • Calibrated S-parameter measurements
    • Real-time frequency-domain measurements
    • Return loss (S11)
    • Cable loss / insertion loss (S21)
    • S11 Between Cursors time-windows the feature of interest
    • Smith charts simplify complex impedance matching problems
    • Normalized TDR traces with adjustable rise time
  • Optimized menu system to simplify common tasks
  • New multicore CPU is much faster than the original CT100
  • 16 times more RAM memory than the CT100

Key Specifications

  • Industry's only high-resolution portable TDR - resolves connector detail (<1 cm separation)
    (At least 8-10x sharper spatial resolution than competing TDR instruments [<100 ps rise time]; catch subtle changes before they cause system failure)
  • Industry's only portable TDR with frequency-domain measurements
    (return loss [S11], cable loss [S21])
  • Much faster and easier to use than VNA with much 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, 6-digit VoP)
  • Industry's fastest intermittent fault detection
    (up to 250,000 samples per second, 500 Hz continuous full waveform capture)


  • Tests all types of cable and connectors
    • Coaxial cable
    • Twisted-pair cable
    • Multiconductor cable (e.g., MIL-STD-1553B, MIL-STD-38999)
  • 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.
  • Aging Aircraft
  • CATV, Power, Telephony
  • Naval / Marine
  • Wireless Infrastructure
  • PCB Impedance Measurements
  • Soil Moisture, Geophysics
  • Tank Farms

Other Great Features of the CT100 TDRs

  • 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.
  • AutoFit™ button scales the display to fit the cable.
  • Configuration library makes repeat measurements as easy as a press of a button.
  • 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.

Ergonomics and Ease of Use

  • Bright 4.3" color 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 Ethernet connectivity.
  • USB peripherals include mouse, keyboard, flash drive, and barcode reader.

General TDR Options

  • CT100B-BNC, 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-SMA, stainless-steel SMA test port
    • CT100B TDR configured with SMA test port assembly. Improved data signal with slightly less electrical overstress protection than the standard CT100B.
  • CT100HF, stainless-steel SMA test port
    • Higher-bandwidth version of the CT100B-SMA featuring the fastest TDR system risetime for testing higher-frequency cables and interconnects.

Standard Accessories (included with instrument)

  • CT Viewer™ 2 TDR Waveform Analysis Software Package
  • CT100B Operator's Manual
  • CT Viewer™ 2 Quick User Guide
  • External AC Power Adapter
  • 2700 mA-hr NiMH Battery Pack
  • Rugged Soft-Sided Carrying Case
    • Plenty of room for calibration accessories, manuals, and optional small form-factor keyboard.
  • Calibration Verification Pack
    • Precision coaxial test cable and BNC/SMA adapters necessary for verifying TDR instrument calibration and performance.
  • NIST-Traceable Calibration Certificate
  • Standard 12-Month Limited Warranty
