CATV Products

Riser Bond
The Model 1205CXA is the choice of the CATV and other coaxial industries.

It features a sub-nanosecond pulse width that is able to identify and locate very small faults in cable and cable components.  The sub-nanosecond pulse width is ideal for locating faults which cause micro-reflections that interrupt digital signals.  It can locate previously undetected or unsuspected faults that occur only at high frequencies.

The 1205CXA is used primarily for fault finding but it can also be used for measuring lengths of cable.  This can be helpful for checking incoming reels or to determine how much cable is left on a partial reel.

Other applications include Power, Broadcast, 2-Way, LAN, Cellular, Avionics, and other industries using metallic paired cable.


  • Range Plus - Two button operation that allows the operator to quickly scan the cable under test while automatically stepping through a specific pulse width, vertical gain, and cable length.

  • Sub-nanosecond Pulse Width - Pinpoint minor faults which interrupt digital services and cause signal loss, ingress and egress.

  • Intermittent Fault Detection (IFD) - Monitor and locate hard-to-find intermittent faults using the IFD mode.

  • Dual Independent Cursors - Measure between any two points on the wave-form.

  • Super-Store Waveform Data Storage - Helps reduce downtime in a system. Simply connect the TDR, press "store", and have the system back up and running within minutes. Analyze the waveform later.

  • Waveview Software - Upload waveforms to your computer. Document before accepting new plant, save money when comparing replacement versus repair cost.

  • Rugged, Waterproof Packaging - Helps to keep the 1205CXA on the job, regardless of location or climate condition.

  • Easy-to-use - Logical, step-by-step testing for fault location and diagnosis. Easy-to-use by all levels of expertise.
