Procedure Description
Expected Observation
1
Configure the transmitter to
operate on air with Exciter A
with precorrector settings to:
Non-Linear Precorrection =
ADAPT
Linear Precorrection = BYPASS
Then connect the spectrum
analyzer to the transmitter band
pass filter output directional
coupler.
2
Configure the spectrum analyzer
as follows:
Start Frequency = 746 MHz
Stop Frequency = 824 MHz
Resolution BW = 100 KHz
Video BW = 300 Hz
Sweep = Auto
Sweep Points = 10001
Amplitude Reference Level = 10
dB
Amplitude Attenuation = 30 dB
Then measure 746-824 MHz with
Exciter A on air.
Less than -13dBm/100 kHz
3
Change the following spectrum
analyzer settings:
Start Frequency = 824 MHz
Stop Frequency = 894 MHz.
Then measure 824-894 MHz with
Exciter A on air.
Less than -38 dBm/100 kHz
4
Change the following spectrum
analyzer settings:
Start Frequency = 894 MHz
Stop Frequency = 1850 MHz.
Then measure 894-1850 MHz
with Exciter A on air.
Less than -13 dBm/100 kHz
