Introducing our New E20/20 Step Time Domain Reflectometer. This model is a significantly enhanced version of our 20/20 TDR. Customers were amazed by the clarity of the traces and features in the 20/20 Step TDR introduced in 2004. It outperformed even the Tektronix 1502C Step TDR, but users asked for even more. We took 8 years of customer input and combined it with18 months of engineering and testing to produce the E20/20 Step TDR. The result is a dramatically improved user interface, enhanced LCD display, new easy to use keypad with function LEDs, USB PC interface, and more. The new E20/20 TDR is now clearly the world’s most powerful and user friendly hand-held step TDR. Combined with our new ETDR PC VisionTM Software for uploading and archiving traces, and creating and downloading cable lists to the E20/20 TDR, no other TDR on the market offers comparable complete professional TDR package.
