Maximum number of samples in ADCpro?

Other Parts Discussed in Thread: ADCPRO

Mr Hupp,

Do you have any versions that allow continuous data acquisition (without any phase lag)? We need to be able to record data using an ADS 1281 for several days.  If not, is there any documentation for the plugin or ADCPro so we can make our own changes? Also, do you know of a way that we could pull the modulator output directly?

Thanks,

Jared Hainsworth

    Mr Hainsworth -

    Currently, ADCPro allows for continuous acquisition in terms of repeated acquisition cycles.  Within the acquisition cycle, the samples are contiguous.  In continuous acquisition mode, the single acquisition cycle is repeated, so there may be samples between cycles that are missing.

    This operation mode is due to the limitation of memory on the hardware and the data transfer to the PC.  Real-time data transfer requires faster transfers or more memory to store the data.

    In terms of documentation, the plug-in files (LabView VIs) should be pretty well documented on the block diagram if you want to view them.  The firmware and ADCPro have some documentation, but you would need the source files.  We are happy to provide these to you if you wish to modify

    You can use the Data Recorder plug-in (loaded by default in the ADCPro shell) to record the data in either single or continuous mode.  In continuous mode, the file name will be incremented by appending a number to the end of the filename.

    For the modulator output, ADCPro is not designed to capture or take in this data.  You could configure the EVM using the setup given in the user guide, but this probably won't function correctly using ADCPro and may either freeze or hang.

    Regards,

    Greg
