Internal Preamp; Ref Position - Agilent Technologies X Series Manual

Internal Preamp

Accesses a menu of keys that control the internal preamps. Turning on the preamp gives a better noise
figure, but a reduced TOI to noise floor dynamic range. You can optimize this setting for your particular
measurement. The LowBand selection needs to show "(3.0 GHz)" for all versions of the N9000A and
"(3.6 GHz)" for the other models.
See "Internal Preamp" on page
This is only available when the selected input is RF.
