CNG Instruments
The NoiseWave NW-CNG instrument improves the speed and accuracy of BER testing by automatically setting precise, stable, SNR (signal-to-noise), CNR (carrier-to-noise), and Eb/No ratios for a user supplied signal. Eb/No generation and measurement for BER (bit error rate) testing is a labor intensive task which is prone to error and inaccuracy. Inaccuracies in Eb/No generation lead to inaccurate and inconsistent BER vs. Eb/No data. This is a problem for the device, modem, receiver, or system manufacturer and for the customer trying to verify performance. The precision, speed, and repeatability of the NW-CNG eliminates this problem and reduces test time.
The NW-CNG can be controlled manually for engineering and laboratory testing or remotely via GPIB or Ethernet for automated production testing. This series achieves the highest reliability using NoiseWave’s proprietary noise generator, broadband amplifier, and solid state variable attenuator technology. Using NoiseWave’s true AWGN noise modules, it achieves a minimum noise crest factor of 18 dB, allowing the user to test very low bit error rates.

Applications
OPTIONS
Option 75: 75 ohm impedance instead of 50 ohm
Option AGC: Automatic Gain Control. The AGC can maintain a precise stable ratio for an input signal which is varying in power. This option is often used for testing with signals received from a satellite or broadcast.
