Re: System that output consist of multiple conditions by using If Condition
Assuming "A", "B", and "C" are numeric outputs from a calculation, you can use a formula node. Here is a quick example based off of your (somewhat confusing) notation. It may need altered slightly,...

Re: RT timing problem after using counter pulse train
Hi Bob, Actually, on the RT system, the "wait until next multiple" and the "wait" RT functions have µs accuracy. When we started the development, we tested using a timed loop versus timing with a "wait...
View ArticleRe: acquisition FPGA
Try using a timed loop rather than a while loop on your FPGA diagram. You are not generating samples at a regular internval inside of a while loop, but inside of a single cycle timed loop you will. See...

Hi All, I'm hoping someone out there can satisfy my curiosity. I have been porting over some code from Matlab to LabVIEW and came accross a difference in the two implementations of the Hann function....

Hi Rene, Thanks for the info I thought I could use 2 daq tasks for the same analog input for example one waits 10k samples (continuously data logging by 100ks sampling rate) other 300ks samples (3s) to...

The easiest way would be to use the DAQmx Configure Streaming. With that function, you set up DAQmx to log all of the data straight to a TDMS file. You don't have to do anything except tell it where...

The Ramp by Samples is the one I have used. Once you have the array of ramp voltages you can play through it in either direction to ramp up or down. And yes you will need a loop because you aren't...
View ArticleRe: Outputting Analog Ramp Voltages
I just had a thought, how long it the time that you are going to be using to generate the entire ramp? I have been assuming that it was a long period -- like over multiple seconds. If the ramp is...
View ArticleRe: Difference between the Matlab and LabVIEW Hann (Hanning) functions
It did cross my mind but I validated the LabVIEW code for the Matlab Hann, alsoo it states in the Matlab documentation the window is over 0<= n 0<= N, so I don't think it's an indexing difference...

The queuing of data is quite powerful since you break up the processes. However, I would make a major change to your program. For the Analog Input, do not use the express VI. Setup the analog input...
