The NC346E is a coaxial calibrated noise source for precision noise figure measurements, operating from 0.01 to 26.5 GHz with an ENR of 19 to 25 dB. It features an APC3.5 male connector, a maximum VSWR of 1.50:1 from 0.01 to 18 GHz, 1.50:1 from 18 to 26.5 GHz, and a maximum current draw of 30 mA. The device includes a built-in regulator, operates with +28 VDC ±2 VDC input, and maintains a voltage coefficient of less than 0.002 dB per percent voltage change. Its temperature coefficient is less than 0.009 dB/°C over an operating range of 0°C to +55°C. The unit is supplied with NIST-traceable calibration data and a calibration report covering return loss up to 40 GHz. The physical dimensions are 0.50 inches in length.
The NC346 Series is designed for precision noise figure measurement applications. Each module’s low VSWR reduces multiple reflections and significantly increases the measurement accuracy for most noise figure test configurations.
