Patent attributes
Techniques are provided for calibrating signal currents in a radio frequency signal generator system, such as an arbitrary waveform generator system. A device comprises a current measurement circuit and a current imbalance correction circuit. The current measurement circuit is configured, during a calibration process, to measure a first current in a first signal path of a radio frequency signal generator, and to measure a second current in a second signal path of the radio frequency signal generator. The current imbalance correction circuit is configured to adjust a current level in at least one of the first signal path and the second signal path of the radio frequency signal generator to correct for an imbalance between the measured first current and the measured second current.
