Dears,
I have question about spectrum analyzer. I detected some signals on 1800Mhz and if i turn off GSM900 station this signal not appeared. So i asked our vendors they answered "this signal is created input of spectrum analyzer". So then i installed band pass filter between spectrum analyzer and receiver antenna, filtered GSM900 signals. After the installing filter/blocked 900Mhz signal/ 1800Mhz signal disappeared. Is it possible? Any one faced such kind of problem?
