Hello, I checked polaryztion, cables, Tx power and re-aligned the link. Nothing has helped. I’m going to replace ODU-s on both sides…
BY the way, Is there any way to check IF radio transmitter is working? In ericsson i can simply do a loop on the ODU and check Rx signal. But I have a link 1+0 made on Nokia 23Ghz antennas , and on one of the end there is no Rx level shown. I replaced the radio radio cause i thought that maybe it is receiver fault, but it didnt help. Other possibility is that on second radio transmitter is faulty. And i wonder if there is any way to do it? Link is made on FIU-s. Thx for sugestions.
