Key Path
Reference Level
Sets the reference level value used for amplitude measurements. The reference level is the
amplitude power or voltage represented by the top graticule line on the display. Changing
the value of the reference level changes the absolute amplitude level of the top graticule
line. The reference level (in selected amplitude units) can be set with the step keys, knob,
or numeric keypad.

Enables you to manually set the RF input attenuation level. You are able to set the input
attenuation value in 1 dB or 10 dB increments. Attenuation can be changed using the step
keys, the knob, or the numeric keypad. When using the step keys, the left and right arrows
increment the attenuation level by –1 and +1 dB respectively, and the up and down right
arrows increment the attenuation level by –10 and +10 dB respectively.
