Features / Key Benefits

• 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 hardto-find intermittent faults using the IFD mode.

• Dual Independent Cursors – Measure between any two points on the waveform.

• 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.

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

• Rugged, waterproof packaging – Rugged, weatherproof casing helps keep the 1205CXA on the job, regardless of location or climate conditions.

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