Configure sampling rate of PXIe-5162

[RobertSTR]

Hi, I have a 4ch PXie-5162 digitizer. I want to use only 2 channels. From the datasheet I read that with 2 channels enabled it should sample at 2.5GS/s but labview says all the time that max is 1.25GS/s.

I put a separate  "niscope Configure Vertical .vi" and disable here  the channels I do not use but it takes no effect.

How to configure the digitizer to get max sample rate with 2 channels?

I think I have the answer. When  sampling 2 channels only, channels specified as active have to be 0 and 2, then I get 2.5GS/s. When I select 0 and 1, sample rate is 1.25GS/s.

Hi！Do you know how to store sampling data at high sampling rates（1.25GS/s）
