hi, what is the noise floor atainable with your
spectrum analyzer? You can try reducing the
frequency bandwidth, and increasing the RBW.
If you know the exact frequency of the signals
to be measured, it is suggested to reduce the
frequecy and RBW sufficiently to get a clear
signal. However, if -60db is the best you can
get with lowest RBW and frequency span, it may
be difficult to measure the signals. By the
way, which spectrum analyzer are you using?
(make and model)?
