SECTION 4 OPERATING INSTRUCTIONS
4.5.3 Output Level Offset
Output level offset means a function to offset a set level and a displayed level against the level to be actually output.
When the output level offset is activated, each level value will be expressed by the following equation:
[Actual Level] = [Set/Displayed Level] − [Level Offset Value]
For example, if you set the output level to −30 dBm after setting the level offset value to +12 dB, the display will
indicate −30 dBm, but the actual output level will be −42 dBm.
To set a level offset value, follow the procedure detailed below:
(1) Press the "Ofs" [F4] key in the main menu (1) to open
the "Offset" menu.
(2) Select "Level offset value" by pressing the "↓" [F2] key
(the level value will be highlighted).
(3) Set a level offset value via the number keys, and the
step keys and rotary knob in the Edit.
When setting offset value via the rotary knob; at first
change the value via rotary knob, then press the [Level]
key, and at last press the unit key (dBm/dBµ) in this
order. The setting is determined at pressing the unit
key.
While the output level offset state last, the characters "L-Ofs" appear on the Output Level indicator, indicating that
the signal generator remains in output level offset state.
To clear the output level offset, you enter 0 dB by following the procedure already described for setting an output
level offset value.
If you need to verify the actual output level while the output level offset state continues, press the [Shift] key and,
then, keep on holding down the [Rel Level] (Cur Dspl) key. This will allow the actual output level to appear
temporarily on the display.
