Abstract :
The signal/noise portion of the dynamic range of many spectrum measurements can be improved by 10 dB or more by compensating for, or subtracting, the thermal noise and/or phase noise of the device used to make the measurement. Through a combination of careful measurements and straightforward mathematical operations, engineers working on microwave measurements can achieve the high dynamic range required by modern communications systems and other applications such as radar.
