The RF output is protected against overloading by an external signal applied to the RF
output (see
Chapter 5.5.9, "Reverse Power Protection" , on page 232).
Setting the RF level
To change the RF level, press the LEVEL key and enter the desired level. Changes to
the RF level have an immediate effect (without confirmation with the Enter key) on the
output signal.
RF Level
Enters the RF level, considering the level offset (see "RF level vs. RF output level"
on page 215).
Note: Some SW options have specific requirements about the calculation of the level
of the output signal, e.g. the displayed value corresponds to the level at the start simu-
lation time, there are correction coefficients to be applied, etc. In cases like this, the
displayed value in the header of the instrument does not always correspond to the
level at the RF output!
When working with a SW option, always refer to the corresponding documentation for
related specific information.
dBm, dBuV, mV and uV can be used as the level units. The 4 unit keys are labeled
with these units.
Note: The SCPI command sets the level of the "Level" display, i.e. an entered level off-
set is taken into consideration in the level value.
