AMPT
Sets the amplitude parameters of the analyzer. You can modify these parameters to
make the signals under test be displayed with minimal errors in the current window,
easy for you to observe.
Ref Level
Sets the maximum power or voltage that can be displayed in the current window.
Remarks:
The RF link is limited by the maximum mixer level, so when you reduce the
attenuation, the instrument may reduce the reference level to meet the mixer
level limit. When you increase the attenuation, the reference level remains
unchanged.
You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.
