TCU error in Bruker!!
Sigh…..I played with so many parameters to get away with the following error. I was trying to install a pulse sequence on a Bruker Spectrometer with XwinNMR (old Bruker software) which was originally written on TopSpin (latest Bruker software) when this error started popping up every time I tried to optimize receiver gain.
tcu error:
Error in ‘hsqcrexetf3gpsi3d.t22.d’:
line 92 (pc=50, ld=2300):
– FCU2 (rp=16, wp=1690, stat=0X8040):
ignored AQNEXT, busy FIFO is stopped
Finally I talked to one of the Bruker personnel and found out the following solution for the error. Always make a point that you add a line “4u” just after you define a shaped pulse. For example, I had the following line on topspin.
;*********************
(p11:sp1 ph2:r):f1
;*********************
So, I had to add 4u after this line to make it work.
;*********************
(p11:sp1 ph2:r):f1
4u
;*********************
Hope this helps.
