This is a real-time spectrum analyser. On the horizontal axe is
frequency (between 7.4MHz and 8.8MHz), and vertical is level
relative given in dB.
The Level can be changed up/down. Scaling can be changed to
zoom in and out. Average can be switched between quicker
response but more noise to slower response but les noise.
At selection View are 3 choices of view types:
All : show everything
Gauss: only update plot when normal noise is detected
Valid: only update plot when normal noise is detected and the
correct signal to noise (SNR)
These 3 types give you the tools to determine what the spectral
environment looks like. Is the environment clean, is there a carrier,
is there a swept system or is there a pulse-listen system.
