RF Noise Source
NS-3
The NS-3 Broadband RF Noise Generator provides an extremely flat AWGN (Additive White Gaussian Noise) signal from 5 to 2150 MHz. The output level adjusts in 0.1 dB steps over a 30 dB range.The bench-top configuration is standard and an optional two unit rack enclosure is available. The RS232 or USB remote control interface simplifies its use in automated test and factory ATE environments. The NS-3's combination of range, versatility and value make it the ideal general purpose broad-spectrum signal source for bench and ATE applications, including C/N, BER, MER, PER testing and rain fade simulation.
