NI PXI-5122 memory size for continous data presentation

[new_programmer]

HELP!!

I need to figure out the the maximum memory capacity for the PXI-5122 digitazer for live data presentation.  Does it have buffer memory?

Thanks!

Hi new_programmer,

You can query the digitizer memory size by using a property node in LabVIEW, or by reading the attribute in a text-base language.  Does this Knowledgebase help?

Note that the 5122 uses some of its onboard memory for data processing overhead, so not all is available for data.  The 5122 also has two bytes per sample.

You can also stream data continuously from the scope if the memory is not big enough, provided you are not taking data faster than your system can stream to memory/disk (probably maximum of about 50MS/s, but you could get more by tweaking things).  See the NI-SCOPE examples for how to continuously stream, if you are interested.
