At ALBA the standard orbit response matrix measurement with DC corrector magnet (CM) modulation is being upgraded with an AC excitation of the correctors combined with the synchronized beam position monitor (BPM) acquisition data rate at 10 kHz. Several types of excitation waveforms (sinusoidal vs square types) and frequencies have been tested and compared to optimize the measurement precision and repeatability. The data acquisition time of the ALBA response matrix (88 horizontal and 88 vertical correctors) with the new AC method takes 1 minute to complete instead of 7 minutes of the standard technique.
