Expected Uplink Power
The following parameters configure the expected uplink power.
Fig. 2-51: RF uplink power settings
Exp. Nominal Power..., Margin
These parameters configure the expected UL power. Two modes are available:
●
According to UL Power Control Settings
The UL power is calculated automatically from the UL power control settings. The
resulting expected nominal power is displayed for information. The displayed refer-
ence level is calculated as:
Reference Level = Expected Nominal Power + 12 dB Margin
For UL power control settings see
chapter 2.4.9, "Uplink Power Control"
●
Manual
In manual mode the expected nominal power and a margin can be defined man-
ually. The displayed reference level is calculated as:
Reference Level = Expected Nominal Power + Margin
The margin is used to account for the known variations (crest factor) of the RF input
signal power.
Note:
The actual input power at the connectors must be within the level range of the
selected RF input connector; refer to the data sheet. If all power settings are config-
ured correctly, the actual power equals the "Reference Level" minus the "External
Attenuation (Input)" value.
The parameters can be changed in all main connection states including "Connection
Established".
Remote command:
Mixer Level Offset
Varies the input level of the mixer in the analyzer path. A negative offset reduces the
mixer input level, a positive offset increases it. Optimize the mixer input level according
to the properties of the uplink signal.
