Q) Why my set frequency is changed to some strange frequency value each time i load a csv file?
A) during each csv read. the program will calculate the data "natural frequency" using formula freq = clock / number of points. workaround:
1) set your desired frequency after each csv file read.
2) save and load a wave to/from memory button instead from a file
3) enable lock parm feature in utility menu to disable automatic "natural frequency" recalculation.

Q) Why my set frequency is changed after i clicked on another wave button?
A) Each wave button has their own frequency (ampl, sweep parm etc) setting which is saved each time you leave that wave button (by clicking another button) and reloaded when you enter back to that wave button by clicking it
