General Description
The CapturePlus™ II data acquisition system is a development
tool that interfaces a Cirrus Logic evaluation board to a PC-
compatible computer. Digital data is collected in a high-speed
digital FIFO, then transferred to the PC over a USB connection.
Evaluation software is included to analyze the data and dem-
onstrate the ADC’s performance.
The data acquisition system is designed to be easily interfaced
to Cirrus Logic evaluation boards. The supplied host interface
software configures the CapturePlus II interface board allowing
the same hardware to be used with a variety of Cirrus Logic
ADC development systems.
The host interface software includes advanced statistical anal-
ysis functionality. The software was developed using National
Instruments LabVIEW
®
, a software development system for in-
strument control and data acquisition and analysis
applications. The evaluation software permits time domain, fre-
quency domain, and histogram analysis.
