TV220 CableScout Time-Domain Reflectometer (TDR)

Cat No: TV220

UPC No: 783310006763

The CableScout® TV220 from TEMPO Communications delivers all the enhanced features that CATV and Telco technicians and network administrators have been asking for in a TDR for CATV applications. The TV220 finds faults other cable testers can’t.. High bandwidth, high resolution, high SNR and ease of use make the TV220 the only logical choice for digital services. The TV220 tests more of the capacity of your cable, finds faults that are closer to the end and finds faults that are closer together than any other TDR available. The CableScout® TV220 can find those really tough-to-identify problems too, and it’s easy (see examples below). A high performance TDR doesn’t have to be difficult to use. This one makes even the first-time user look like a pro. The TestWizard™ feature automatically finds multiple faults on coax cable. There’s no longer a need to interpret the results; they’re clearly marked. TestWizard™ testing automatically adjusts and optimizes gain, averaging, and pulse width to provide the best possible resolution while maximizing the instrument’s ability to find all the problems on your cable – even small problems missed by most other TDRs.

TV220 CableScout Time-Domain Reflectometer (TDR)
  • Tempo Report Writer: Software Update
  • High Voltage Tolerant: Will not be damaged by high voltages (up to 400V (DC + peak AC).
  • High Bandwidth: Tests more of your system capacity enabling users to pinpoint the faults that can cause micro-reflections which can be damaging to digital transmissions.
  • High SNR: The TV220 also has extremely high signal-to-noise ratio (SNR). Proprietary circuit design and software reduce the noise level so that bumps on the trace represent real faults, not just noise. Events previously difficult or impossible to find, are clearly visible with the TV220. This means that you can clearly see faults further away.
  • High-resolution performance allows the TV220 to locate problem components in the customer drop. The TV220 uses a pulse width of only 1ns, which means the operator can identify multiple events that are less than 2ft apart. This enables the technician to tell which of two components on a cable is causing the problem, even when they are close together. This is particularly important in troubleshooting drops, because components such as splitters and ground blocks can be closely spaced.
  • TestWizard Testing: The most innovative feature in the TV220 is TestWizard automated testing and event marking. Now, instead of meticulously setting up the TDR and then carefully interpreting the meaning of the displayed waveform, you push one button to get a high-resolution, low-noise trace, with the events clearly marked. This means substantial savings in training time and reduced time to get accurate, repeatable measurements.
  • Return Loss Measurements
  • Multiple Event Marking
  • Pinpoint the faults that can cause micro-reflections which can be damaging to digital transmissions.
  • Locate problem components in the customer drop.
