The Model 458-AWGN2 is the ideal solution for injecting Additive White Gaussian Noise (AWGN) for ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing applications. The user may add AWGN on the CO and/or CPE side, depending on their application. The 458-AWGN2 allows for common or independent noise levels on both sides. This line module produces a flat Power Spectral Density (PSD) over bandwidths from 20 kHz to 30 MHz..
This module is plugged into our Model 458-3SLB (3-Slot) or 458-CC-16 (16 Slot) chassis where settings are controlled by a convenient keypad located on the front, RS-232, Ethernet or IEEE-488(GPIB). The modular design of Telebyte’s products allows the 458-AWGN2 to be combined with other line modules for a wide variety of test configurations. This module can also be used to inject AWGN onto real cable..
