The Validator is a precise analog signal generator device. The Validator can either be connected directly to the Ellutia A/D board 37-pin connector through the extension cable or through the terminal board to any other data acquisition device. Four sets of chromatogram data are stored in Validator.
Data are stored in the FLASH EEPROM memory in digital form and are converted to analog data using a 1-bit D/A pulse width modulator. This converter guarantees full monotonicity, good linearity and no missing datapoints. The signal resolution is 20bit.
