I made a vi for the FRA data logging and it is already posted. There is one mistake is showing that, when I am sweeping in log(10steps/decade), in the starting of sweep two three steps it is showing all zero values. like as below
after that it is running correctly
In the plotter which I made is showing this zero values but in the data which is saved the zero values are not there.
In the LIN sweep, there is no problem.
I cannot probe the problem.
Please help it is very important in frequency response analysis
