This command results in a command error. The F'REQ:CW portion of the
command is missing a leading colon. The path level is dropped at each
colon until it is in the F'REQ:h3UI.T subsystem. So when the F'REQ:CW
command is sent, it causes confusion because no such node occurs in the
reset to the root. The corrected command is:
5 GHZ".
Notice that in this example the keyword short formis used. The
command is correct. It utilizes the default nodes of [:Cw] and [LEVEL].
Since default nodes do not affect the current path, it is not necessary to
use a leading colon before POWER.
