TSW1400EVM: Can't get TSW1400_pattern_gen to work

Part Number: TSW1400EVM

Hi,

I want to generate my own pattern file for the TSW1400 to then load it into the HSDCP GUI. 

I therefore downloaded this Support software from the TI Website: https://www.ti.com/lit/zip/slwc110

After successfully running the included MCRInstaller.exe I tried running the TSW1400_MultiTonePattern_v1.exe, but I always get the following error message: "Could not find version 7.16 of the MCR... (picture)."

 The installation of version 7.16 of the MCR  however was successful and the corrisponding folder can be found in (C:)/program files

Note: My system is on Windows 10

Am I missing something obvious? How do I fix this error?

thanks and best regards

    Hi Mario,

    Which version of HSDC Pro are you using? Our latest software (available online) includes pattern generation. Do you need some other kind of pattern generation or is sinusoid all that is desired?

    Hi Chase, 

    thanks for your quick answer. I am currently using version 5.20 of HSDCP. 

    Yes, I want to add a Dither signal to the sine, but I can't find an option for this in the HSDC Pro GUI. I figured I could create a file in which a dither signal is included with the software mentioned above and then load this file into the HSDC Pro GUI via the "Load External Pattern File" Button.

    Hi Mario,

    I've just installed this on my PC and do not see any dither generation supported in this software. The best approach for this is to first define the dither amplitude and then simply add to a sinusoid pattern using either python or MATLAB. We can help out with this if desired.

    The goal will be to have the added dither outside of the band of interest in the output tone and to do this, we will just need to generate a large data pattern (which is within the size constraint of the TSW1400EVM) and then combine with a psuedo-random integer list (which is of the same length as the sinusoid data pattern) generated using python or MATLAB. We will multiply this list of random integers/float values with a scalar to define the dither amplitude before rounding to the nearest integer and then adding this random noise onto the sinusoid pattern.

    Hi Chase, 

    thank you for your answer. I wrote a skript using Matlab, as you suggested. It works and I get significant better results than with just the Multitone Generator included in the HSDC Pro GUI. 

    It is quite a bit more work though. It would be nice if a dither signal generator was added in a future version of HSDC Pro.

    HI Mario,

    Thanks for the update and suggestion! I'll mention it to the software team.
