Abstract
A system for synthetically sampling an input signal to provide a sampled signal includes a sample clock and a mixer. The sample clock is configured to generate a sampling signal having a sampling frequency. The mixer is configured to receive the sampling signal and the input signal, and to output an intermediate frequency (IF) signal by mixing the sampling signal and the input signal. An offset voltage is introduced into the mixer with the sampling signal to provide a baseband image, the offset voltage being adjusted so that the baseband image of the IF signal has the same magnitude as a first harmonic image of the IF signal.
