The Telebyte Model 456 is an instrument that generates shaped narrow band and broad band noise that can be used for testing local loop transmission products such as ISDN, HDSL, T1 and ADSL modems. The Model 456 will accommodate the needs of engineers in the development lab or technicians on the production line. The Model 456 is an ideal companion for the Model 453, Wideband Wireline Simulator, which simulates the transmission characteristics, attenuation and phase, of the local loop. Easy to use front panel selection switches allow the user to select one of eight different noise shapes. Outputs are provided on both GR plus and Bantam jacks.
Power is supplied by a modular wall plug-in power supply.
