Abstract
A signal measurement device and method are provided for receiving an RF input signal using frequency sweeping. The method includes determining RMS power levels of a noise floor of the signal measurement device at respective frequencies from a start frequency to a stop frequency of a swept frequency range; determining values of resolution bandwidths corresponding to the frequencies, the values of the resolution bandwidths being inversely proportional to the RMS power levels of the noise floor at the respective frequencies; performing frequency sweeping from the start frequency to the stop frequency to receive the RF input signal at the signal measurement device; and implementing the determined values of the resolution bandwidths corresponding to the frequencies while performing the frequency sweeping. Implementing the determined values of the resolution bandwidths results in functional sensitivity of the signal measurement device being substantially constant over the swept frequency range, and provides faster sweep times.
