Popis:	The Andeen-Hagerling AH2700A Ultra-Precision 50 Hz-20 kHz Capacitance Bridge is used to determine the magnitude and phase errors of Texas Instrument's DAC8811 16-bit Multiplying DAC. An automated testing method using a USB-SPI interface and LabViewTM to control the DAC is presented. The DAC output magnitude and phase errors are dependent on input code, input frequency, and the input voltage magnitude, and a hypothesis for the dependencies is discussed.
