device, you should use a 75Ω to 50Ω adapter to connect the analyzer with the system under test
and then set the input impedance to 75Ω.
2. Apply Correction

amplitude for optimum display effect of the signal to realize one-key signal search and auto setting
of parameters.
In the process of auto search, The “
Auto Tune
” is shown in the status bar on the screen until
the search is finished.
Some parameters such as the reference level, scale, input attenuation and maximum mixing
level may be changed during the auto search.
