[:SOURce<hw>]:POWer:STARt <Start>
The command sets the RF start level in Sweep mode.
As with the "Level" value entered in the "RF Level" menu, the
OFFSet
value is also taken
into consideration with this command.
The specified value range is therefore only effective if
:SOURce:POWer:OFFSet
is set
to 0. The value range for other
OFFset
values can be calculated using the following
formula:
Minimum level +
OFFSet
... Maximum level +
OFFSet
Parameters:
<Start> float
Minimum level ... Maximum level
The value range for the level setting varies according to the instru-
ment model. The values are given in the data sheet.
