Abstract:
A multiple-output arbitrary waveform generator comprising:an output waveform data generation section for generating an output waveform data signal for an LSI test; an output sequence control section for controlling the output waveform data generation section based on a test sequence specific to an LSI to be tested; and an analog waveform generation section for digital/analog-converting an output waveform data signal outputted from the output waveform data generation section to apply the signals to a plurality of LSIs to be tested, wherein the analog waveform generation section comprises: a gain adjustment section including a plurality of ports via which the analog test signals applied to the plurality of LSIs to be tested are individually outputted to individually adjust gains of the analog test signals outputted via the ports; and an offset adjustment section for individually adjusting offset voltages of the analog test signals.
