High Speed Data Converter (HSDC) Pro Software Output Binary File Format

Roger Backhus

Other Parts Discussed in Thread: ADC3244

Hello,

I'm using the HSDC Pro software and I have to pass the ouput/acquired time domain data to other software for processing.  So, I'm looking through the HSDC Pro Software documentation and I'm not seeing any indication of the format of the output acquired data file.  I was wondering if someone will pass me the binary output file format definition or else a code snippit so I know how to read the file?  I'm using the software with the TSW1400EVM board.

Thank you.

    Hi Roger

    Can you let us know which specific ADC EVM you are using with the TSW1400, and what operating mode if it has multiple possible modes?

    The binary format will be somewhat dependent on the device and mode.

    Best regards,

    Jim,

    I'm using the ADC3244EVM.  I don't think it has multiple operating "modes".  I'm sampling a single channel anywhere from 65 MSPS to 125 MSPS.

    Thanks.

    Hi Roger

    The ADC3244 is a 2 channel ADC. The Save Raw ADC Codes as Binary File saves both channels of data into a single file as follows:

    [LSByte S1 Ch1] [MSByte S1 Ch1] [LSByte S1 Ch2] [MSByte S1 Ch2] [LSByte S2 Ch1] [MSByte S2 Ch1] [LSByte S2 Ch2] [MSByte S2 Ch2] etc...

    The 14-bit values are right justified within a 16-bit (2-byte) sample format.

    Here is an example view of binary data as hex and the resulting in 2-ch column hex format. This data is from a 12-bit converter, with a high frequency signal on Ch1, and no input on Ch2, but the concept and organization is the same as it would be for a 14-bit converter.
