NI5441 Streaming

[AZH]

Hi all, Does anyone have or know if there are examples for streaming of IQ data (complex data) between NI5441 AWG and NI5621 Digitizer for me to refer. 

I wish to write a continuous string of IQ data to the on board memory of NI5441 and then to the NI5621.

Thanks in advance!!!

Hi AZH,

There will probably not be any examples for streaming IQ data specifically between the 5441 and 5621 cards.  Instead, there will be generic examples that work for a lot of different digitizers or different AWGs.  The examples in Toolkits and Modules>>Modulation should prove useful if you have the modulation toolkit.  If you don't, you can use the LabVIEW on-line demo at http://digital.ni.com/demo.nsf/websearch/14f9ce475127ade786256ac60070926c?opendocument to evaluate it.

The Toolkits and Modules>>Modulation>>NI-SCOPE>>MT niScope IQ.vi example supports the 5621.

Generating IQ with two AWGs is also in an example in Toolkits and Modules>>Modulation>>NI-FGEN>>MT niFGen IQ Signal Generation_TClk.vi, which supports the 5441

There are also more specific examples for FM and or QAM modulation in the same folder.  I hope this helps!
