Issue Details

I am making measurements of an oscillator with a very high frequency ~5MHz. Which NI modules would be able to support this type of high frequency measurement?


There are a couple of devices that are generally used for high frequency measurements listed below.

For compactDAQ or cRIO platform, the NI 9775 module allows up to 20MHz for its sampling rate
NI 9775 

For the PXI platform, the PXI 6115 sampling rate goes up to 10MHz
PXI 6115

For even higher sampling rates: the FlexRIO line or NI 6570 could be options depending on your application.

Additional Information

Note: This is not an exclusive list of all NI hardware that could support high frequency measurements. The list should be used as a starting point for finding the appropriate hardware for your application. For more information, please contact NI Sales at  (877) 387-0015.
