Connect to the base station.

NOTE: The autoranging feature under [Setup], [Range Control] that is built into the test set helps ensure accurate measurements by changing front-end amplifier gain as needed. This might be, for example, when a strong signal threatens to overload the test set. When this occurs, the noise floor rises (as gain is decreased), then falls again when the strong signal stops.

If you prefer a fixed noise floor, you can disable autoranging in two ways using the Setup function within Channel Scanner:

On [Range Ctrl] select Hold to fix the noise floor at the current level. A subsequent strong signal-even outside the measurement range-may cause an inaccurate reading due to overloading the front-end of the test set.
On [Range Ctrl] select Max to fix the noise floor at the current level until a strong signal comes in. In that case, the floor will rise to maintain accuracy, but will not return to its lower level after the strong signal stops.
