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/dB

µ) 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.
