| 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 interrupted. The
new CNG-1-800/2700 covers 800 to 2700 MHz, with the same accuracy
as our 70/140 MHz units! In the CNG-1-800/2700, noise generation, attenuation, and
power measurements are done at IF, so there is no degradation to ratio accuracy.
Total noise bandwidth is 125 MHz, wide enough for virtually every application while
still providing a high noise power spectral density. |
