Stream data to disk (LabVIEW RT and NI PXI-5122)

[Gerald_Schaller]

I'm planning to acquire a signal at a rate of 20MS/s during 10 Minutes. I thought about buying a PXI Chassis containing a digitizer PXI-5122 and a controler PXI-8174 running LabVIEW RT. Is it possible to stream the data to disk or to another HOST PC with those requirements ? Does anybody have onother hardware solution ?

Thanks in advance for any answer ?

Hello There,

I have seen some answers to your question in other forums too. While agreeing on the fact that RT really is not essential from the requirement specification you gave, I would recommend going for the latest controller which is PXI-8186.
PXI-8186

One important thing to keep in mind. Streaming to disk while acquiring at 20 MS/s for 600 secs (10 mins) means 20*600 = 12000 MS = 24000 MBytes = 24 GB.
