PXI
DAQmx Filter Delay function help with MATLAB
Hi Guys!
I have been using MATLAB to communicate to my PXIe-1082 chassis with the PXIe-4464, and PXIe-4461 installed.
A problem I've ran into is the filter delay in samples on the PXI devices is not constant across devices so I'd like to be able to assess the status of the filter and be able to find out how many samples it will delay the signal by.
My first idea was to use the functions in the image on matlab, but the output came as a number that did not make sense (refer to image). I was wondering if there is anything I'm doing wrong, and if there is a better way to asses the filter status with NIDAQmx functions.
Another method of getting rid of the delay was to have a task that includes all of the input channels I was going to use for a test and have that task synchronize the captures so the samples line up with each other. Is this possible with NIDAQmx functions or should this be done in NI MAX?
Thanks!
Alex
