NoiseWave’s NW346 Broadband calibrated coaxial noise source is ideal for Noise Figure measurement applications.
Available in 6,15 and 23 dB ENRs (Excess Noise Ratios), the NW346 is ideal for a wide range of noise figure measurements and built in test applications.
The NW346 features an excellent VSWR reducing measurement uncertainty, in addition to stringent temperature and voltage stability. The unit features an industry standard profile housing.
Each noise source comes with VSWR on and off data and a calibrated ENR report traceable to NIST. Flatness is better than +/- 1.0 dB over the frequency range. The NW346 is available with a variety of connectors. Standard operation is from +28 Vdc with 30 mA maximum current draw.
The NW346 is a precision noise standard that is economically priced with delivery typically from stock. Alternative voltages, output levels and frequencies are also available
