5.18.4 Max Mixer Lvl
Enables you to set the relationship between the highest signal that can be displayed (the
reference level) and the input attenuation. The relationship applies whenever the
Attenuation is set to Auto. The relationship is that the attenuation is given by reference level
minus the max mixer level. For example, as the reference level changes, the input
attuanator changes to ensure that a signal at the reference level does not exceed the Max
Mixer Lvl
setting.
When the TOI measurement is on, this key controls the maximum mixer level,
independent of the previous setting of
Max Mixer Lvl located under Amplitude. When the TOI
measurement is Off, the previous maximum Max Mixer Lvl is restored.
Setting
Max Mixer Lvl to Auto sets the maximum mixer level to −30 dBm.

5.18.5 Optimize Ref Level
Sets the reference level to place the tones near the top of the display. When input
attenuation is set to Auto, pressing Optimize Ref Level sets the input attenuation according to
the auto rules described in Max Mixer Lvl, based on this reference level. You may want to
trade off analyzer noise and analyzer-induced distortion by manually changing the
attenuation setting from this starting point.
