1. Sunlite E1 BER-Tester

he SunLite E1's versatility is enhanced with such features as the choice of 75 OHM unbalanced or 120 OHM balanced connectors and power supplied by either rechargeable NimH or two AA alkaline batteries. The combination of convenience and power makes the set useful in the outside plant, central office, customer service center, product development lab, and corporate communications center.

The SunLite E1's powerful capabilities, compact package, and low price makes it a clear choice for equipping an entire staff of technicians.

Weighing a mere 0.3 kg, the SunLite E1 is the world's smallest full-featured handheld 2.048 Mbps transmission test set. The SunLite E1 simplifies 2.048 Mbps E1 testing while providing more diagnostic power than is available in many larger portable test sets. The SunLite E1 can be utilized at an exchange, multiplexer, regenerating repeater, or 2.048 Mbps terminal.

The SunLite E1 offers such capabilities as :

  • 2.048 Mbps transmit, receive, and external clock
  • E1 bit error rate testing
  • Level and frequency measurements
  • +6 to -43 dB receiver input sensitivity
  • Terminated, protected monitor, high impedance modes
  • Drop and insert capability (M or Nx64)
  • VF monitoring and analysis
  • Programmable Send Frame Words
  • CAS signaling
  • G.821, G.826, and M.2100 analysis
  • Histogram analysis
  • Alarm Generation/Error Injection
  • Propagation Delay measurement.
  • Store up to 10 test results and 10 user profiles
