Rx and Tx Power Offset

To obtain accurate results, compensate for any external attenuation or gain by using the
Rx Power Offset or Tx Power offset submenus under the Amplitude main menu key. In power
offset mode, the compensation factor is in dB. (External attenuation can be created by using
an external cable or an external high power attenuator.)
Press the Rx Power Offset or Tx Power Offset submenu key and use the keypad, the arrow
keys, or the rotary knob to enter the desired offset value. When using the rotary knob, the
value changes in increments of 0.1 dB. Using the Left/Right arrow keys changes the value in
10 % increments of the value shown on the Scale submenu key. When using the Up/Down
arrow keys, the value changes in the increment shown on the Scale submenu key. When
using the keypad, enter the new value then press Enter or the dB submenu key to set the
value. The power offsets for Tx and Rx are displayed in the instrument settings summary
column on the left side of the measurement display.
