In the Standalone (SA) scenario, these parameters are controlled by the measurement.
In the Combined Signal Path (CSP) scenario, they are controlled by the signaling appli-
cation.

Dual Carrier Separation
In the dual carrier measurements, the center uplink frequency of carrier 2 equals the
center frequency of carrier 1 plus carrier separation value. Exception: at the upper end
of an operating band, carrier 2 uses the center frequency of carrier 1 minus carrier sep-
aration value. If you configure one uplink channel, the other uplink channel is config-
ured automatically.
Use the value of 5 MHz for adjacent channels.
In the Standalone (SA) scenario, this parameter is controlled by the measurement. In
the Combined Signal Path (CSP) scenario, it is controlled by the signaling application.

Expected Nominal Power
Defines the nominal power of the RF signal to be measured.
Configure it as follows:
●
multi evaluation measurement: peak output power at the DUT expected during the
measurement interval
●
TPC measurement: peak output power at the DUT expected during the measure-
ment. Even if you start the measurement with minimum UE power, consider the
maximum power expected at a later stage of the measurement.
●
PRACH measurement: peak output power at the DUT expected for the first pream-
ble. For subsequent preambles the expected power is calculated automatically
from this value and a power steps limit setting, see also
While the combined signal path scenario is active, this parameter is controlled by the
signaling application. Configure the signaling application, so that it calculates the
expected nominal power from the UL power control settings (expected nominal power
mode = "According to UL Power Control Settings"). Do not use the manual mode.
The "Ref. Level" is calculated as follows:
Reference Level = Expected Nominal Power
+ User Margin
The actual input power at the connectors (i.e. the "Reference Level" minus the "Exter-
nal Attenuation (Input)" value, if all power settings are configured correctly) must be
within the level range of the selected RF input connector; refer to the data sheet.
