Is value of default channel power ignored in Bruker systems for the shaped pulses?

Hello, been editing a wiki page on the subject and this question occurred:

For a Bruker pulse sequence in the following context:

pl3:f3
(p3:sp3):f3

Is it important to set instead 120 db to f3 power before the sp3 statement and restore to pl3 afterwards? That is:

pl0:f3 !where pl0 is set to 120 db
(p3:sp3):f3
pl3:f3

I've seen this pattern before and I wonder if it is actually important for any reason or a particular system.

Thanks!

For a Bruker pulse sequence in the following context:

pl3:f3
(p3:sp3):f3

Is it important to set instead 120 db to f3 power (or rather attenuation - in the Bruker scheme of things) before the sp3 statement and restore to pl3 afterwards? That is:

pl0:f3 !where pl0 is set to 120 db
(p3:sp3):f3
pl3:f3

I've seen this pattern before and I wonder if it is actually important for any reason or a particular system.system. - Is there any danger in not nulling the default power before the pulse?

Thanks!

db, i.e. full attenuation - zero power
(p3:sp3):f3
pl3:f3

I've seen this pattern before and I wonder if it is actually important for any reason or a particular system. - Is there any danger in not nulling the default power before the pulse?
