High power decoupling Carr-Purcell-Meiboom-Gill echo train

Code for Avance spectrometers with xwinnmr 3.5 operating system

; hpdecqcpmgall.av (xwin-nmr 3.5)

; written by Stefan Steuernagel, February 2003
; pulse program for quadrupolar CPMG sequence with high power decoupling
; samples continuously, including ALL pulses and ringdown delays
; for work up use AU program au_qcpmg to store echos only
; for summation of echos au_qcpmgadd may be used
; for more information check comments in AU programs
; may be used with digmod digital
; in edasp, connect logical channels F1 and F2 to same hardware channel
; in edasp, logical channels F1 and F2 must have the same offset (OFSX1 = OFSX2)
; in eda, O1 and O2 must have the same value

; !!! recable 1H channel F3 direct to probehead !!!
; !!! do not connect via the proton preamplifier !!!
  
edasp for Carr-Purcell-Meiboom-Gill echo train
; limitations:
; pulses and delays must be integer multiples of dw * 2, 
; e.g. for dw = 1 us, all pulses and delays must be integer multiple of 2 us
;parameters:
;ns : 16 * n
;d1 : recycle delay
;d3 : time to allow pulse ringdown, 10 to 100 us
;d6 : enter duration of FID
;pl1 : =119, not used
;pl2 : =119, not used
;pl12 : RF power level for proton decoupling
;pl21 : RF power level for CPMG
;p3 : 90 degree pulse
;p4 : 180 degree pulse
;p25 : dummy pulse, not used for acq.
;l22 : number of echos to be acquired
;cnst1 : set td to number of acquired complex data points
