Dear all,
While running the t1ir experiment, I noticed a potential issue related to
the number of extra scans.
I set ds = 4 and ns = 8. For the first FID, the 4 dummy scans were
applied correctly.
However, starting from the second FID, the NS scans appear to be executed
twice, instead of the expected sequence of 4 dummy scans followed by 8 real
scans.
To better illustrate this behavior, I used short delays in the vdlist and
recorded a video demonstrating what I observed.
Additionally, when I change the first line of the pulse program from
(1 ze) to (1 zd), the total experiment time is reduced by approximately half.
Has anybody observed this behavior?
Best regards,
Weixing
