The
20/20 TDR is “Step” Time domain Reflectometer designed
specifically for measuring High Bandwidth Copper Media.
21st Century RF, broadband,
telecommunications and network cabling systems demand a
higher quality installation practice and fault-free
transmission media. AEA
Technology designed the 20/20 TDR to meet today’s needs
for coaxial and twisted pair cable installation
verification and for fast, efficient troubleshooting.
Combined with AEA’s TDR PC Vision TM
software, included with every TDR, any technician can now
save plots, upload to a PC and document network or system
installations. The
20/20 TDR is compact, rugged and light-weight to meet
mobile technicians’ demand for high-quality, accurate
instrumentation that fits on their belt.
Additionally, AEA Technology makes multiple models
to meet the needs for connecting to coax with BNC, N or F
connectors, or the twisted pair cables with RJ45 or Telco
clips. The
“Network” models combine both RJ45 style Network and
Coax connectors to service Voice, Data and Video
media in one instrument |
