On-Board Memory

Hi,

We have a NI PCI-4461 data acquisition module. In the process of our measurements, we are saving 10,000 samples on its on-board memory, and retrieving it later.

Recently I was looking for a second DAQ card, and found out that according to NI's website, the on-board memory of the PCI-4461 card is only 2047 samples.

 

Could anyone please tell me what am I missing here? Maybe the number on the web is not actually the real number of measurements (samples) I can save on the board's memory?...

 

Thanks in advance!

Hi Nirit,

 

The on board memory is 2,047 samples, it is just transferred via Direct Memory Access (DMA) to the PC when it fills up.
