I am using an example vi program to run sine sweep through NI PXI 5412 and it works fine.
However, now I need to collect 2 signals using NI PXI-5105 for this generated sine sweep. I understand that due to large size of data, I might need to use "niScope EX Fetch Forever.vi" or "niScope EX Fetch In Chunks.vi" etc. I need to send a digital trigger to a NI SCOPE code from the NI FGEN code. I found that "niScope EX Fetch Forever.vi" does not actually send any trigger, rather obtains pretriggered samples. Also, I have to save the multi-channel data from onboard memory of PXI 5105 to my internal hard-disk. Can I use any digital triggering option on any of these example continuously fetching data?
Thanks

I have found the following example that continuously save data which appears to a modification of "niScope EX Fetch Forever.vi" for multiple channels. This program runs well and saves data in binary file format. I have attached the link for the file here.
I still need to trigger this NI-SCOPE file using a digital trigger from NI-FGEN. Can anyone give any suggestion for this?
