5.7 Test the Optical Input Signal
Test the optical input before configuring the module. First, confirm the optical input signal by using the optical signal power
meter according to the technical specifications. This step ensures the device receives an input signal within specified -5
to +3 dBm input range. Then access the optical signal to the module, at the same time the module optical input indicator
should show a green light.
5.8 Test the RF Output Signal
After confirming, that the module’s input optical signal is within the normal range, login into ASMM’s web interface to set
the appropriate RF gain / slope parameters. A spectrum analyser or RF signal meter can be connected to the RF output of
the FRAS or through the test point located on the front panel of the FRAS module. Make sure that the RF output does not
exceed 40 dBmV for 80 channels of RF.
CAUTION!
When testing the RF signal at TP port, ensure that all unused RF ports are terminated with a 75 Ω load to reduce the
potential errors during testing.
