ADCPRO

ADCPro™ is a modular software system for evaluating analog-to-digital converters (ADCs) without the need for expensive logic analyzers and complex analysis routines. Used alone it is suitable for performing analysis on data sets captured from ADC testing; when paired with a Texas Instruments ADC evaluation module (EVM) and suitable data capture card, it becomes part of a powerful evaluation package.

ADCPro software from Texas Instruments will simplify the tasks of collecting and analyzing ADC data, and ease evaluation. With it, you can easily set up an evaluation system that may not exactly replicate the manufacturer's system, but still arrive at meaningful results that can be compared to system requirements.

• Ability to save and recall data sets
• Modular design allows additional EVMs and Tests to be supported
• Time, Histogram, and Frequency Domain Testing

Without any hardware, ADCPro can be used to analyze datasets - this can be an easy way to evaluate the tool. Data can come from two different plugins included in the distribution:

• TripleGen - a three channel function generator
• FileReader - an EVM plugin that reads data files stored in the ADCPro format

Using TripleGen as a data source, you can explore the functionality of ADCPro and learn about the test capabilities of the program.

The ADCPro data file format is tab-delimited text and compatible with most spreadsheet programs. If you have data collected from an existing ADC, you can easily format it for reading by FileReader and use ADCPro to analyze the data.

The test plugins that come with ADCPro are:

• Data Monitor - display the data you've loaded or acquired
• MultiScope - a multichannel oscilloscope for time domain analysis
• MultiHisto - a multichannel histogram test with DC noise analysis
• MultiFFT - a multichannel FFT plugin that displays your data in the frequency domain, and calculates signal-to-noise (SNR), total harmonic distortion (THD), signal-to-noise plus distortion (SINAD or THD+N), and spurious-free dynamic range (SFDR).

Plugins for connecting hardware to ADCPro are available for some Texas Instruments analog-to-digital converters. See the related products section for those evaluation packages that are compatible with ADCPro.
