7
 		For an over the air measurement, connect an antenna and an external filter to the RF input.
 		The external filter is necessary to eliminate out-of-band signals that would otherwise reduce the dynamic range of measurements in the band of interest. The effect of the out-of-band signals is to raise the noise floor, possibly hiding some or all of the signal of interest.
9
 		Set the level to Autoscale.
  1. [Level]
  2. [Autoscale]

The marker value appears in the upper right.
 Pressing [Marker] on the left menu displays the Marker menu on the right. Pressing Marker on the right menu selects your marker number. Marker numbers cycle from 1 to 2 to 3 to 4, and back again, each time you press this key.
