Scale/div: The scale can be set in 1 dB steps from 1 dB per division to 15 dB per division. The value can be changed using the keypad, the rotary knob, or the Up/Down arrow keys.

Scale changes the y-axis scale. This applies to the Spectrum view only. When in any other view, the display is “--”.

Power Offset: Choose power offset to automatically adjust for the loss that occurs through any external cables, attenuators, and couplers. The power can be offset from 0 dB to 100 dB. Press the Power Offset key, enter the values, and press the dB submenu key.

Auto Range: Pressing this submenu key toggles between On and Off. This function adjusts the reference level automatically when Auto Range is activated.

Adjust Range: Pressing Adjust Range will trigger reference level detection once and also set Auto Range to Off. The instrument will no longer automatically trigger reference level detection. The user must press Adjust Range to do this when necessary until Auto Range is turned back on.

Units: Select either dBm or Watts as the power unit.
