AMPTD Y Scale
disadvantage of bypassing the preselector is increased LO emission levels at the front panel input port.
Internal Preamp
Accesses a menu of keys that control the internal preamps. Turning on the preamp gives a better noise figure, but a poorer TOI to noise floor dynamic range. You can optimize this setting for your particular measurement. The instrument takes the preamp gain into account as it sweeps. If you sweep outside of the range of the preamp the instrument will also account for that. The displayed result will always reflect the correct gain.
Key Path: AMPTD Y Scale, µW Path Control
Example: :POW:MW:PATH MPB
Dependencies: Key is blanked if current mode does not support it.
Key is grayed out if mode supports it but current measurement does not
support it.
Key is blank unless Option MPB is present and licensed. If SCPI command
sent when MPB not present, error –241, "Hardware missing; Option not
installed" is generated.

[:SENSe]:POWer[:RF]:MW:PRESelector[:STATe]?
Example: :POW:MW:PRES OFF
Bypasses the microwave preselector
Notes: The ON parameter sets the STD path (:POW:MW:PATH STD)
The OFF parameter sets path MPB (:POW:MW:PATH MPB)
Preset: ON

Dependencies: Preamp is not available on all hardware platforms. If the preamp is not present
or is unlicensed, the key is not shown.
The preamp is not available when the electronic/soft attenuator is enabled.
Preamp controls and settings are not available on the E6607C. If any preamp
commands are sent to the E6607C the following error will be generated:
