Over–the–Air Measurements (OTA) – LTE FDD Option 370, LTE TDD Option 371, 5GTF
Option 377 (CPU2 Only)
How to Set Up Over–the–Air (OTA) Mode Settings
The Spectrum view in 5GTF uses a center frequency that is +2.6 MHz offset
from the carrier's center frequency. This is done so that FieldFox can
capture the necessary xPBCH (physical broadcast channel) information to
demodulate the signal. Be aware that all of the instrument's displayed
numbers are rounded to three significant digits (e.g., 5.0026 GHz is
displayed as 5.003 GHz).
IMPORTANT! When you select a multiple CCs (e.g., CC0, CC1, etcetera)
and record data, you may actually see other cell signals that do not have
sufficient power to be displayed, but are still detectable. When multiple
component carriers are selected, the results of the component carrier (CC)
with the highest power are displayed. Refer to
