Setting up shaped pulses
From NMR Wiki
Bruker
On Bruker systems the statement for a shaped pulse is similar to:
(p3:sp3 ph3):f3
Here it is intended to apply to channel f3 (channel 3) a pulse of duration p3 microseconds using phase table ph3.
Usage of :sp3 in the statement implies these things:
- the pulse is shaped
- sp3 is the variable with a value of maximum power for the pulse
- variable spnam3 contains the (string) name of the waveform file
- any power value for channel f3 set before is ignored (???) and sp3 is used instead
In order to use a shaped pulse in the experiment:
- the waveform must be created, if it does not exist
- value of sp3 needs to be determined based on the calibration
