Procedure For A Higher Accuracy Receiver Calibration For Use In mm-Wave Noise Figure Measurements

The VectorStar™ Noise Figure Option 41 employs a cold source method that uses terminations and absolute power measurements to provide noise figure measurements for frequencies from 70 kHz to 110 GHz. This cold source noise figure measurement removes the errors associated with mismatch differences between the hot and cold states of the source, simplifies calibration and traceability, and provides traceability paths through the power sensor. The traceability information is usually readily available, compared to what can happen with the calibration requirements of the noise source. Download the full application note for more on this accurate method of noise figure measurements up to 110 GHz by using the Vector Network Analyzer platform.
