Front Panel Key Backlight
The on/off state and the color of the backlights of some keys at the front panel
indicate the working state of the spectrum analyzer. The states are as listed below.
1. Power Switch
 Flash on and off alternatively, in breathing state: indicate the unit is in
stand-by state.
 Constant on: indicate the instrument is in normal operating state.
2. Auto
When Auto is pressed, the backlight turns on. The instrument starts sweeping
within the full frequency range, searches for the signal with the maximum
amplitude and moves it to the center of the screen. Then the backlight turns off.
3. Meas**
The backlight of Meas turns on when any of the advanced measurements is
enabled and stays on until all measurement functions are disabled.
