I am trying to use EasyWaveX to create a arbitrary waveform that has a frequency component that is lower than 1 Hz. I cannot get the software to display the full waveform of any expression less than 1 Hz.
It appears that the waveform display always displays 2 Pi radians of the output equation. This is fine if the signal you are generating is over 1 Hz. However, if I have a wave that is longer than 2 Pi, only 2 Pi radians of the waveform is displayed and the rest of the signal is truncated and not displayed.
See the equation with a 10Hz frequency riding on a 0.5Hz signal where only the first half of the total waveform is displayed.
This case is trivial as the second half would be a mirror image, but if you were working with a 0.1 Hz frequency, then 90% of the total desired waveform would be unavailable for the engineer to view.
Let's look at a waveform with a freq of 0.1 Hz.
When the frequency goes lower than 1 Hz, the arbitrary wave becomes less than 2pi (aka 0.1pi in my example). However, it appears that the EasywaveX software is limited by it's display software to be unable to display waves longer than 2 pi (or any Sub-Hz signal). As in this case of the 0.1Hz signal ... where 90% of the wave is not displayable.
If you are doing very low frequency work, EasyWaveX appears to be unusable.
If there was a way to adjust the graph display to display 4 Pi radians of samples (or more) to fully display the entire waveform would seem to be a simple way to correct this deficiency.
(Changing the number of samples or frequency in Settings appears to have no effect on the waveform display.)
Has anyone else seen this problem, have a solution I have not seen in displaying Sub-Hz waveforms with the Siglent Signal Generators?
I have been well satisfied with the hardware that I have purchased from Siglent, but this seems like a major oversight in the EWX software for any engineering project dealing with very low frequency projects ... presuming I haven't missed something after trying to get it to work for a couple days.
All comments welcome towards a solution!
Thanks!
