Hi
We are thinking to use the PXIe-6396 module for fast data aquisition of analoge signals and two quadrature encoders. Because of this, the counters in the PXIe-6396 are already used for the encoders, but we need 5 additional counter inputs. We were then thinking to add the PXIe-6614 counter module, but are not sure about the synchronization of the two cards. Which is the most elegant way to synchronize the analoge inputs, the counter inputs on the PXIe-6396 and the counter inputs on the PXIe-6614?
Also, is it preferrable to add a reconfigurable digital I/O module instead of the mentioned counter module? As far as we understand, we could use the FPGA on the module to implement counter inputs as well.
We have a source frequency of up to 25 MHz and would like to use the NI-DAQmx python library (FPGA programming would be done via Labview obviously).
Thank you for your advise!
Best regards,
Stephan
