calculating power level

For some reason the shape tool has some sort of glitch that I can't calculate a power level for a wurst 10 ms pulse 180 rotation for a a 522 max gamma ~ for over 3000 Hz. I think I've done this many years ago but can't find my notes on it. Is there a way to calculate this? Thanks. R

calculating power levellevel with stdisp

For some reason the shape tool has some sort of glitch that I can't calculate a power level for a wurst 10 ms pulse 180 rotation for a a 522 max gamma ~ for over 3000 Hz. Hz, with an option "Analyze adiabatic shape".

It insists it is not an adiabatic shape.

So I tried opening the same file shape tool in XWIN-NMR shape tool and the same problem occured but this time it gave me the Hz covered in maximum gamma when I included the degrees of rotation as well as the time for the pulse. it covers a 3ppm bandwidth etc.

I think I've done this many years ago but can't find my notes on it. Is there a way to calculate this? Thanks. R
