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. Applications • Noise figure measurement • Built-in test equipment (bite) Specifications Noise output rise and fall times Less than 1 ìs Noise output variation with temperature Less than 0.01 dB/°C Noise output variation with voltage Less than 0.1 dB/1 %ÆV Operating temperature 0 to +85°C Input power +28 VDC at 30 mA max Data Sheet NC5000 Series 18 GHz to 110 GHz Options NC5opt01 +15 VDC NC5opt02 TNC bias connector NC5opt03 Right-angle BNC bias connector NC5opt04 +28 VDC with regulation Stabilized noise output for ±2V variation NC5opt05 Output isolator • Military applications • Radiometers
