Help with e******* RBS 3418/3518

[atese]

Hi you guys..

Does anyones know if in the RBS 3418/3518 there is an analog output port to use to connect an spectrum analizer to see input signals from antennas with gain from the internal amplifiers?

I need to see the inputs signals before the TRX, but after the internal amplifiers.

I understand this equipment has optical fibers port, but I have only an analog spectrum analizer.

I´ll apreciate any help.
