Scale: Press this submenu key to change the scale of the y‑axis in the RF measurement displays. The range of the scale can be set from 1 dB/div to 15 dB/div in steps of 1 dB/div.

Power Offset: Enter the power offset to automatically adjust for the loss or gain through any external cables, attenuators and couplers. The power can be offset from 0 dB to 100 dB in either direction. Press the Power Offset key, then enter a value using the arrow keys, rotary knob, or numeric keypad.

Note: When using the keypad, the submenu keys will change to Units keys (dB) of External Loss and External Gain, as illustrated on the left, below the Amplitude menu. Enter a value, then press the appropriate Units key to make your selection. A negative offset value in external gain equates to the same amount of external loss. For example, entering –1.0 dB in Ext Gain is the same as 1.0 db of Ext Loss.

Auto Range: Press this submenu key to toggle the Auto Range function between On and Off. When set to On, the instrument adjusts the reference level automatically for each sweep.

Adjust Range: Press this submenu key to perform a single reference level adjustment. Auto Range is automatically turned Off.

Units: Press this submenu key to set the units for all measurements and summary tables in either dBm or Watts.
