Can I build a waveform with variable dt ?

[lv00220]

Hi,
I want to generate a waveform to use the smart waveform
functions. Unfortunately the acquired data to build my waveform have variable dt. I do not only want to display my waveform (I know I could use a xy graph in this case) but I also want to do some calculations provided in the "Wavefrom Operations" palette?

Is there a way to achieve this except interpolating
the values along constant time steps on the x-axis?

Thanks in advance
Jochen

Looks like the answer is negative - the waveforms supposed to have uniform x spacing and that's the reason why all those waveform functions are so "smart" - they use this uniform feature of the waveforms... So you'll be obliged to use xy-data functions or interpolate your data.

What functions are you wanting to use from the Waveform Operations palette? Many of them have corresponding versions that don't require waveform datatype input.

One thing to be careful of is that some functions (like FFTs for instance) aren't valid if you have a varying dT.
