I used a simulated Oscilloscope (PXIe 5105) for code development.
I noticed that the timing is not correct for the acquisition.
For Example, the Sample Rate was set to be 10kS/s, and record length is 8MS.
So the acquisition time should be 800s (10kS/sX800s=8MS).
In the small vi I wrote, the simulated device was initialized and configured first. Then after a software trigger was set and initialize, a while loop was used and in the while loop the backlog was fetched immediately. When the vi was started, the backlog size gives 8e6 immediately. This is clearly not right.
I have read on http://www.ni.com/tutorial/3698/en/, that a simulated device created in NI-DAQmx 8.3 and later do simulate timing, which means Task read and write operations will simulate the actual time they would take to complete as if they were being run on a physical device. But PXIe5105 is not a DAQmx device.
So is it true that Simulated Oscilloscope does not simulate timing?
Will this feature be supported in the future driver, like DAQmx driver?
Environment:
LabVIEW 2016, NI Scope 18.7, Signal Express 2015
