RRC Filter BW
Sets the Root Raised Cosine (RRC) filter bandwidth. Normally, the filter bandwidth is
the same as the symbol rate of the signal.

3.5.8.3 Limits
Lets you set up the test limit for channel power or power spectral density.
When DVB-T radio standard is selected in SA Mode, this functionality is disabled,
and the input signal is instead compared against a pre-defined spectrum mask.
In LTE-A FDD/TDD and 5G NR Modes, this feature is not supported.
In MSR Mode, this feature is not supported, because the power of each carrier may
be different.
Power Limit
If Power Limit state is ON, this setting is a threshold to determine whether the real
measured channel power can be passed or not. If real measured channel power
exceeds Power Limit, the channel power test fails, otherwise, it passes.
If Power Limit state is OFF, the channel power test always passes.
