DIG-100M1002-PCI is a PCI-bus compliant digitizer board that features: 10-bit resolution, up to 100MSPS (10nsec) conversion speed, sampling 2 channels simultaneously. In addition, it features with the PASS/FAIL judgment functionality by comparing input data with the set standard data (mask data) one by one. The large (32M data) on-board memory and bus master transfer function allow continuous data acquisition to be performed at high speed for a long period. The automation of the measurement is facilitated by factors such as various sampling control and waveform judgment function based on mask data. The mask editor software is attached as a tool to generate comparison waveform data.
