RF1 Ref Level
Sets the expected receiver level for RF1 when you wish to specify different values for RF1 and RF2 inputs.
Otherwise, this value is set by pressing Atten > Ref Level.

Attenuation
Manual: Enables you to define the attenuation level(s) for RF1.
Auto: Enables the PXT to calculate and set the optimum attenuation value based on the reference level
(and other internal parameters) set by pressing Atten > Ref Level.
Adaptive: Automatically adjusts the attenuation when the overflow (OVF) alarm is detected.
For example, if you wish to increase the number of uplink RBs, effectively increasing the UE power
consumption, the PXT automatically adjusts the attenuation to compensate for this change. See Adaptive
Attenuation – More Information.
Setting the Attenuation to Adaptive
enables three options:
• IDLE_ADJUSTER
• CONNECTED_ADJUSTER
• OVF_ADJUSTER
To ensure your measurement results are displayed correctly, compensate for
external loss or gain by setting Atten > More > RF1 Input Power Offset.
For more information on how power level settings can affect the ability for the UE to connect, see UE is
not connecting.
