Real time streaming and saving data is possible? [HSDC Pro]

Other Parts Discussed in Thread: ADC12J4000, ADC16DX370, LM15851

Hello.

 

I want to ask about real time streaming and saving data system.

 

The product which i saw is like this :

ADC12J4000 Evaluation Module : http://www.ti.com/tool/adc12j4000evm

ADC16DX370 Evaluation Module : http://www.ti.com/tool/adc16dx370evm 

LM15851 Evaluation Module : http://www.ti.com/tool/lm15851evm

As you can see in the 'user guide', these three product have evaluation system and that system use the HSDC Pro software.

 

I want to know how to do the real time signal acquisitions.

In the User Guide chapter 4 (low level control), I think that 'the function which can save the binary data which show in the screen' is exist.

But I want to do this more than computer memorys.

for example,

- signal carrier is 400MHz with BW 20MHz,

- sampling rate is 4G sample / sec with 12 bit ADC

- Real time acquision with 60S

in this case the total data for saving this is : 4G * 12 bit * 60s = 2880 G bit / min = 360 G byte / min

and i want to save this binary data in my computer.

is it possible to do this by using this ADC evaluation module and HSDC Pro?

or it just save the data which showed in memory size

(I think that in this case, the real time streaming is not possible. than what is the maximum size of this possible data size? it is dependant on my computers memory size?) 

 

Thank you for reading this questions.

 

 

  • Kang,


    All of the ADCs listed use the TSW14J56EVM evaluation platform for data capture.  Please see the related EVM product folder for more details.  In general the platform can support up to 256Msamples @ 16 bits wide.

    The platform is not capable of streaming data to the PC, it only stores the samples to memory.  The HSDC Pro software then displays this data on the PC.
