Adjusting the Scale and Amplitude Settings

Enables you to change attenuation settings. When RF Attenuation Auto is ON,
the RF Attenuation is set by adjusting the acquisition. As the acquisition is
lowered, for example from -10 dBm to -30 dBm, the FieldFox assumes that you
are looking at low-level signals. The RF Attenuation value is automatically
lowered in 5 dB steps to allow low-level signals to be viewed. The RF
Attenuation value is never automatically lowered below 5 dB.
How to set Scale/Amptd
