You can also set the attenuation manually. TheR&S Spectrum Rider provides
attenuation in the range from 0 dB to 40 dB in 5 dB steps.

4. Press [AMPT] key.

5. Select "Att/Amp/Imp" softkey.

6. Select the "Manual Att" menu item.

The R&S Spectrum Rider opens an entry box to define the attenuation. Two
methods are provided to fill in the input fields:
● Directly with the number keys
● Using rotary knob
While you can enter any number you want with the number keys, using the
rotary knob is coupled to a certain step size in most cases.
If you use the rotary knob to change the attenuation, i.e. the step size is 5 dB.

7. Enter the attenuation you need.

The R&S Spectrum Rider shows the current attenuation level in the "Parame-
ter View".
