I'm a little bit confused about setting o1, in the case of a solid sample First o1 is the offset of the transmitter frequency so sfo1 = BF1 + o1 In my case I have to set Sfo1 = BF1 so I must set o1 = 0 Hz Second there is another way to optimize o1 whish is by applying gs and looking the fid, adjusting o1 until we have a good exponential decrease of the fid. In this case o1 value may not be 0 Hz. Does the second technique is valid in solid stat experiences? And which one I have to use?

It seems those two methods are different. If you just want SFO1=BF1, then just set o1 equal to 0Hz. But if you want to optimze the transmitter frequency to obtian a good spectrum ,I think the second way is right. For this aim, I think you try the third method as following: If there are several peaks in your spectrum, you just put your o1 cursor on the peak which you want its offset is 0 Hz.:)

I think that you want to say that I have to calibrate the peak at 0 Hz, but if I you do this, sr value will change and not o1. - silvernmr (Mar 09 '11 at 06:17)
