E1 Transmission Test Set


Electrodata's E1-LITETM is one of the most economical E1 transmission testers on the market today. The E1-LITE is designed with full E1 transmit and receive functions perfect for installing and troubleshooting E1 lines and equipment. Built to the same exacting standards of other Electrodata products, the E1-LITE is designed to autoconfigure to the line coding, framing format, and test pattern; perform bit error testing using standard E1 test patterns; identify error and alarm conditions; measure signal frequency and level; display 30 timeslot channel signaling; perform drop and insert operations; and includes a timing reference jack to allow clock slip detection and measurement. The E1-LITE is designed to test across the full E1 band or test individual timeslots.


The E1-LITE uses thirteen LEDs to display normal line conditions, alarm or error conditions, and test set battery condition. A keypad allows auto-configuration, test set up, timeslot selection, error injection, and results monitoring with the touch of a finger. A built-in speaker allows timeslot monitoring, and a headset jack allows monitoring and voice operation with headsets using standard 2.5 mm plugs. The easy to read 2-line by 16-character liquid crystal display makes set up and results reading simple.

The Complete Package

The basic instrument E1-LITE comes complete with a PS-3 battery eliminator / charger and technical manual. Test cables and other accessories suitable for your specific requirements can be purchased directly from the factory. The E1-LITE is covered by a standard one-year warranty.
