ADS4249EVM: How to use the TSW1400 Board to upload the 1GB Data Sampled by ADS4249 to the PC for further analysis

Part Number: ADS4249EVM
Other Parts Discussed in Thread: ADS4249,

Hi:

I purchase the TSW1400 board and ads4249 evaluation Board. And I use the USB2.0 interface in my PC to connect the two boards.

I use the channel A of the ADS4249 to sample the data generated by the AWG(arbitrary wave generator) for 1 second using a 250MHz Sine Waveform(0.6Vrms) as the clock.

The ADS4249 works in the 125MSPS speed as I see from the HSDC pro software. And the ADC firmware is ADS Bit Wise 2CH.

How could I use the TSW1400 to capture the data and store in the 1GB DDR2, and then upload the data of the 1GB DDR2 to the PC for analysis?

Thanks

User,

Download the latest version of the High Speed Data Converter Pro GUI User's Guide (SLWU087D) on the HSDC Pro GUI product folder on the TI website and see section 3.1.1 for information regarding your question.

Jim,

Thank you for your advice.

I manage to do it.

I wonder if there any DC coupling ADC Evaluation Board for the TSW1400?

The ADS4249EVM is a AC Coupling. And Once I capture a 470ns Gaussian pulse with a 10 kHz repetition frequency, the waveform would distort.

User,

Since most customer test with AC coupling, this is the default setting on all of our LVDS EVM's that I know of.
