ADS5560EVM: Continuous storage of data stream

Marcel B

Part Number: ADS5560EVM


Dear TI-Team,

we're using the ADS5560EVM in conjunction with the TSW1405. Is there a way to get a continuous stream of data from the TSW1405 evaluation board and where can I tap the data?  We would like to save the data separately and analyze it later. We have tried the GUI and the options given there and looked through the Automation.dll. In a separate approach we tried to tap the data directly via the serial bus (USB), but that did not work.

The bash commands used were:
stty raw -echo <dev/${USB} (Linux)
type com5 (Windows 10)

Regards,

Marcel

    Hi Marcel,

    HSDC Pro has the option to save the data separately to be analyzed later. This can be found by selecting 'File '-> 'Save Integer I32 Codes as CSV file'. There is not an option to stream data in real-time.

    Hello Amy,

    the single acquisition provided by the HSDC Pro does not help us, because there can be up to 2 seconds between the bursts to be analyzed, and the burst can have a length of only 400 µs with a frequency of up to 5 MHz. We can see the signal via the average acquisition FFT but there only the last data set gets saved. Is it possible to reprogram the FPGA on the TWS1405 to realize a continuous data acquisition?

    Thanks for your help.

    Regards,

    Marcel

    Hi Marcel,

    Are you looking to average the FFT of a large number of samples, or to average the FFT over multiple data captures?

    If you are looking to average the FFT over a large number of samples, based on the details you gave above about 1G of memory is needed. The TSW1405 is limited by 64K of memory, so this is not an option for this capture card.

    If you are looking to average the FFT over multiple data captures, then you can use the capture option in HSDC Pro to write this data to a bin file.
