System error 50502 using PXIe 6368 Cards with PXIe 8880 controller

[ASIM_BHATTI]

Hi all

I am using 07 PXIe-6368 DAQ Cards with PXIe 8880 Conroller (8 GB RAM) installed in PXIe-1078 chassis for simultaneously acquiring 100 channels data in finite mode (with Trigger mode Enable  ) with maximum sampling rate i.e. 2 M samples/s/channel. I am currently using NI DAQmx ANSI C routines to acquire this data.

The problem is that i want to simultaneously acquire 0.45 sec data for each analog input channel for each trigger pulse it receives. This requires about 900 K samples/channel to be acquired for every trigger pulse. However, the program gives an error (status code: 50202) that operation can not be completed as specified. Below 600 K samples/channel, this program works fine however this does not fulfill my requirements.

With PXIe-8880 controller (8-core processor) installed with 8 GB RAM, 250 GB SSD and PXIe-1078 chassis, is this required acquisition is more than the capacity of this  system or there is something i can do in my C programming using some C APIs to enhance the performance of my system?

Thanks & Regards

Hi

Thanks for help. I think the problem is not in coding (may be i am wrong) as i have created a task in NI MAX with these acquisition specifications (mentioned in my first post) and when i try to run this task, it crashes.

Thanks
