The Telebyte Model 4901 Multi-Output Noise Simulator provides 2 to 24 independent noise channels in a powerful, 4U-high industrial PC. The modular system holds up to 6 (2 or 4-port) AWG cards and can be expanded by adding more AWG cards, noise injectors and other components as needed. A user-friendly configuration software allows the user to select and build impairment models common to DSL network implementations. A wide variety of custom crosstalks (including ADSL2+ and VDSL2) as well as impulse noises (such as REIN, SHINE and PEIN) can be created. In addition, user-defined files in several formats (such as MATLAB and Excel) may be imported. Optional noise modules automatically setup standards-based testing for TR-114, TR-100 and more.

Offering the only fully-compliant TR-114 solution in the industry.

 * Impulse and crosstalk noises must be carried out on two different AWG cards. ** Splitting the noise on one port provides correlated noise on 2 ports. In this case, up to 12 independent noises may be injected simultaneously if all ports are utilized for this purpose.
 

Refer to individual Noise Library datasheets for hardware required to run tests within that library.
