Carrier Aggregation
Your Anritsu test instrument supports single-input single-output (SISO) as well as 2x2 and
4x4 multiple-input multiple-output (MIMO) systems. If a single antenna is active, the
Component Carrier measurements illustrated in
Figure 6-15 are aggregated from the entire
modulated contents of the LTE signal. When two or more antennas are active, the
measurement results displayed represent the QPSK modulated signal on the Physical
Broadcast Channel (PBCH).
1. Press the
Measurements
main menu key.
2. Press the
Over-the-Air
submenu key.
3. Press the
Carrier Aggregation
submenu key to display the OTA Carrier Aggregation
table. Press the key again to display the Carrier Aggregation menu. See Figure 6-15 .
4. Press one of the five Component Carrier (CC) submenu keys to set it up for
measurement.
5. Configure each Component Carrier as needed. Refer to “Component Carrier Menu”
on page 6-47 .
6. Press the
TAE
submenu key to turn on or off the Time Alignment Error measurement.
7. Press
Back
to return to the Over-the-Air menu.
EMF
Refer to “LTE/TD-LTE EMF Menu” on page 8-2 .
Note
Figure 6-15 illustrates a 4x4 MIMO configuration. In 2x2 MIMO, there are two
transmitter status indicator dots for each active Component Carrier. Refer to
“Carrier Aggregation” on page 6-18 for a description of the measurement data.
