      Dear freinds
      hope you all will be fine in life!I am again requesting the respected friends to reply regarding the problem which i am facing in my simulation.

      i want the plot between PSD(dBm/Hz) and frequency as shown in the attached screen shot.But the plot just shows a straight line. when i get the plot between dBm and frequency,it shows the exact shape of a plot.What is the problem and why i am not getting a plot like display between dBm/Hz and Frequency?
      is anybody will help me???i will be very grateful to you for this help
      Regards
      Jawad Mirza

      The signal power is low, most likely because of the 50 dB attenuator right before the Analyzer. (50dB is quite a bit are you sure that is correct?) The signal power is most likely less than the sensitivity of the analyzer, either fix the signal and make it stronger or lower the sensitivity bounds for the analyzer by right clicking and heading to the component properties.
