How to Acquire Data at High Rate for Several Seconds?

[Jhon_2001]

Hello Everybody,

I am using a PCI 5152 with 64Megs of memory per channel. I am also using Labview 7.1 in WinXP. My PC is a Quad Processor Computer with  2GB of Ram.

I need to acquire data for several seconds as follows: I am triggering at 1ms and for each trigger I want to save the first 200us  of data at the highest possible rate (more than 200MHz).

I have developed the code attached but I keep getting the error -1074116198 (buffer overwrite).  Any ideas or suggestions are welcome

Thank you very much  in advance.

Jhon.

Hi Jhon,

Could you please provide a screenshot of the front panel for your VI when you run the program and receive the error (I want to know what each value is set to). Are you able to run the program without error when you decrease the record length and/or sample rate? Additionally, what are the values of the Records Fetched and Records Acquired indicators when you receive the error? Can you please provide a screenshot of the actual error message you are receiving as well? Finally, I am curious to know why you are taking your min record length value and dividing it by the period (reciprocal of min sample rate)? I look forward to hearing back from you soon and reproducing the issue you are seeing.

Cheers!
