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 117 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 107, you
can continue your measurement.
