Count on the Noise Leader Precision Calibrated Millimeter-Wave Wave Guide Noise Sources The NC5000 Series noise sources feature outstanding stability, switching speed, and ripple-free response over standard waveguide bands. The high stability of the NC5000 Series allows these units to be used in place of cumbersome gas tube noise sources. Ripple in the output of noise sources has a direct effect on measurement accuracy, so Noisecom has tailored the response of the NC5000 Series so that ripple is minimized throughout the specified frequency range. The NC5000 Series is available with noise output of 15.5 dB for instrumentation (noise figure meter) applications, as well as in narrow and full waveguide bands with 15 to 25 dB enr output. The standard input bias connector is bnc female; others are available.
