Power Results
Total carrier power, total PSD and total format carrier power are displayed in the
lower window. Total format carrier power is total power of carriers of the same Radio
Format. If there is no carrier of the corresponding format, it is not displayed. Thus,
items in the total format power table changes depending on the carrier
configuration. Since the metrics window of MSR, LTE-Advanced FDD/TDD and 5G
NR is slightly denser than that for common CHP, the vertical positions of total power
and power spectral density are raised.
Carrier Info: LTE-Advanced FDD/TDD and 5G NR Modes
The following diagram shows the Metrics Window in the Carrier Info view for LTE-
Advanced FDD/TDD and 5G NR. The Power Results window is replaced by the
carrier info table.
The text window displays the following results:
Total Carrier Power
This is the total power of all the carriers with carrier measure state setting to On. The
power is calculated by integrating across the bandwidth declared by the Carrier
Integ Bw parameter for each carrier and then totaling the sums. The total
integration bandwidth is shown as part of the result. This will be the total of the
Carrier Integ Bw of the carriers used in calculating the total carrier power. If the RRC
Filter is on, then the integration bandwidth used is (1 + alpha)/T where T = 1/(Carrier
