3 Spectrum Analyzer Mode
3.3 Channel Power Measurement
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
Integ Bw) multiplied by the number of carriers with carrier measure state setting to
yes.
RF-BW
Displays the total bandwidth from the lowest carrier to the highest carrier, whether
their measurement states are on or off.
Carrier Power
This is the power in all the currently defined carriers. If the carrier is with
measurement state being on, the power will be absolute. If the carrier is defined as
not having power present, the power will be shown up as dash. The power is
calculated by integrating across the bandwidth declared by the Carrier Integ Bw
parameter. The integration bandwidth is shown as part of the result. This is the value
of the Carrier Integ Bw for the carrier unless the RRC Filter is on, then the
integration.
Integration Bandwidth
Displays the channel bandwidth of each carrier.
Filter
Displays whether RRC filter is used or not.
Offset Frequency
Shows the offset frequency from the carrier reference frequency in multi-carrier
measurements. The carrier frequency display type determines whether the relative
frequency or absolute frequency will be displayed.
Sub-block
For intra-band non-contiguous spectrum operation, the sub-block concept is
introduced, which refers to one contiguous allocated block of spectrum for
transmission and reception in the intra-band non-contiguous aggregation mode.
We support two sub-blocks. It displays which sub-block the carrier belongs to in the
intra-band non-contiguous aggregation mode. The column is displayed when the
carrier allocation mode is non-contiguous.
Measure
Shows whether the carrier power presents or not.
The highlighted row changes according to whether Carrier Result or Select Carrier is
changed. The highlighted row and these keys are not coupled.
