insures that the amplitude level of the ALC is kept within
optimal limits.

-
the attenuator setting is set to the value of POW :ATT and left
there. The *RST value is ON.

Sets and queries the center power for power sweep. Default units
(and units for query response) are determined by the UNIT:POWer
command.
The coupling equations for power sweep are exactly analogous to
those for frequency sweep. Power sweep is allowed to be negative,
unlike frequency sweeps. See

Sets and queries the output level. Default units and units

POWer : MODE?
Sets and queries the setting of the power sweep mode switch. If in
the sweep mode then the output level is controlled by the start,
stop, center and span functions. If in the fixed power mode then the
output is controlled by the POW C: LEVEL] command. The *RST value
is FIXed.
