Connection of TSW1200EVM and ADS4226EVM

Hi,

The TSW1200 hardware is capable of simultaneous capture from two channels.  The TSW1200 User Interface was not written to process more than one buffer of data at a time, however.  The firmware int he FPGA is set up in four banks of memory of 16K samples each, and it is possible to capture from a 2-channel EVM with data from the two channels loaded into memory simultaneously.  Then you would be limited to 32K samples max for each of the channels. 

But the TSW1200 software was not written to set up that mode of operation and process two results.  Also, we do not provide the Labview source file for the TSW1200 user interface, as it is a very large folder of code and support for the code would be a problem.

We *do* provide upon request a kernal of Matlab code for a minimal TSW1200 interface that *can* capture and process two channels of data simultaneously.  The Matlab code is primitive compared to the Labview based GUI, but the Matlab kernal is meant for users who wish to just get the data captured adn into their PC so that they can then begin to develop their own post-processing.  The Matlab code was not created to be a GUI, but just .m files that would then require a Matlab license to use.

To use the Matlab-based interface, you would install the Labview-based GUI first to check out the setup.  This would install the VCP(virtual com port) that both the Labview-based GUI and the Matlab code require.  And also the Labview-based GUI would find the com port that the operating system assigned to the TSW1200 and this piece of information is hand-edited into the Matlab code to go an open the right com port.  Then the Matlab code can setup for simultaneous capture and display an FFT result for both channels.  And from this point, you can add to the Matlab code to save the sample data, or the processed result, or to develop your own post-processing as you desire.

For the Samtek connector, there is a zip file fo the physical design package for the ADS4226 EVM in the project folder  http://focus.ti.com/docs/toolsw/folders/print/ads4246evm.html for this device under support software, see literature number slac459.  This includes a spreadsheet for the bill of materials, listing HMTSW-105-07-G-D-.240 as the part number for the connector on the EVM.   For the TSW1200, the bill of materials is included in the User Guide for the TSW1200 rather than as a separate zip file, see literature number slau212a.  http://focus.ti.com/analog/docs/litabsmultiplefilelist.tsp?literatureNumber=slau212a&docCategoryId=6&familyId=390  It lists QSH-060-01-F-D-A as the part number for the mating connector.

Thank you for your reply.

I made a mistake while asking you about connector. Sorry about that.

What I reallly wanted to know was not about connectors but cables that can be used to connect two evaluation boards.

In my native language, the word, connectors and cables can have the same meaning in some context.

Therefore, when I checked HMTSW-105-07-G-D-.240 and HMTSW-105-07-G-D-.240,

the salesman told me that those connectors cannot be work directly.

So, my original quesition should have been what cables do I should buy for connecting ADS4246EVM and TSW1200EVM?

And I hope to receive the Matlab code as soon as possible.

Thanks.

Richard, it was successful.

I was able to see one tone signal in the FFT window.

I just connect 10 MHz into the J19(CLK_IN) so that I was not able to see the single tone at first.

We have to connect an appropriate clock which has the same sampling frequency with the ADC.

ADS58C28 is working well with 160 MHz input clock so J19 should be connected with a 160-MHz clock source.

There are lots of things that I've not finished in my project.

Thank you.
