4.2.13.5 Out of Band Emissions Test Results
The following plots show the typical results:
5
Change the following spectrum
analyzer settings:
RBW = 30 Khz
Start Frequency = 722 MHz
Stop Frequency = 722.1 MHz.
Then measure 722 – 722.1 MHz
with Exciter A on air.
Less than -38 dBm/30 kHz
6
Attach a notch filter between the
spectrum analyzer and the output of
the bandpass filter.
Change the following spectrum
analyzer settings:
RBW = 100 kHz
Start Frequency = 698 MHz
Stop Frequency = 746 MHz.
Then measure 698-746 MHz
Less than -38 dBm/100 kHz
7
Repeat steps 2-6 with Exciter B on
air.
Results should be consistent
with those from steps 2--6.
