NOTE
You can use the
LIMIT
hot key to analyze your measurements with the user-definable
limit and Pass/Fail indication. See “Setting limit for RF tests” on page 227 for more
information.
Spurious emissions
Out-of-band emissions are unwanted emissions immediately outside the channel bandwidth resulting from
the modulation process and non-linearity in the transmitter but excluding spurious emissions. The Spurious
Emissions measurement is to identify and determine the power level of out-of-band spurious emission within
the necessary channel bandwidth and modulated signal measured at the RF port of the Base Station.
Setting measure setup
After configuring test parameters as described in the “Configuring test parameters” on page 214, you can
continue your measurement.
