Abstract
Method and waveform generator for generating at least two signals. The signals are generated by separate channels, with each channel having a numerically controlled oscillator and a digital envelope generator, whose outputs are multiplied and fed to a digital-analog converter. The signal from the digital-analog converter is multiplied with the signal from a local oscillator for generating pulses with an up-converted carrier. The phases of the numerically controlled oscillators are changed between pulses in order to adjust the phase of the up-converted carrier. This allows to generate pulses where the up-converted carriers have a defined phase relationship.
