CNG-70/140 Carrier to Noise Generator

SKU: CNG-70/140 Category:


The CNG-70/140 is a fully automated test instrument that sets

and maintains a highly accurate ratio between a user-supplied

carrier and internally generated White Guassian noise.

The instrument operates over a wide range of power levels.

The modular design provides one or two totally independent

channels covering 50 to 180 MHz. The instrument utilizes dBm’s
proprietary microprocessor controlled attenuator with 0.015 dB
resolution, so resolution uncertainty is less than 0.008 dB.

Typical attenuator error is less than 0.02 dB over its entire

frequency range and attenuation range.

The CNG corrects for noise density and signal level variations

over frequency, and integrates the actual noise power over the

user defined signal bandwidth. The carrier signal path is never
