total memory of all waveforms exceeds the allocated amount of memory on the FPGA

[chw1]

I am using the niRFSG Allocate Arb waveform.vi to bring in a 6G waveform file. 

 I am getting errors such as:  total memory of all waveforms exceeds the allocated amount of memory on the FPGA.

 Is there a way to adjust the FPGA memory on the PXI 5646 to accommodate the 6G waveform data file?

 Here is a setup

Hi cosburn,

I don't think you are breaking up the waveform into enough smaller chunks to fit into memory.  You can check the total size of the arb memory on the PXIe-5646 using the property Arb:Memory Size (http://zone.ni.com/reference/en-XX/help/371025N-01/rfsgproperties/cnirfsg/).  Make sure that the waveform you are trying to allocate to memory is smaller than this size as discussed in this document: http://zone.ni.com/reference/en-XX/help/371025P-01/rfsg/streaming_waveform_data/.

Hi Luke,

I have not considered breaking up the size of the waveform.  That makes good sense considering the RAM is 512K X 2 and is probably filling up while leaving the remainder unaccounted. 

Your response provides me with some great direction to fix this issue.

thanks
