4900-NS1 Universal Noise Generation Software

Industrial Noise Generator for Realistic G.hn Device Testing

Testing with realistic noise environments is important to verify the physical layer performance of devices that use G.hn technology (e.g., Powerline Communications, Gigawire/G.hn Access and G.hn over coax). Reporting the correct Mean Squared Error (MSE) value and calculating the corresponding SNR is a key indicator for low or error-free data traffic performance.

The Universal Noise Generation software supports Arbitrary Waveform Generators (AWGs) and noise from 20 kHz to 200 MHz on two independent noise ports. The AWG is used with the Telebyte Differential Noise Injector to inject noise with a high impedance and a crest factor greater than 5. Allows injection of differential noise on each device on the link segment or one device with combined noise  (time + frequency domain) from two channels.

Alien Crosstalk or Impulse Noise may be used for system or pre-deployment testing in the lab.
