Performing carrier aggregation measurements
Carrier aggregation enables a maximum of five multiple LTE carriers to be used together in order to
provide high data rate required for LTE-Advanced. Component carriers to be aggregated can be intra-
band contiguous, intra-band non-contiguous, or inter-band. The JD780A series provides carrier
aggregation measurements supporting for all the different modes with carrier aggregation bands
added to the channel standard. This functionality is activated if the license for the option 031 LTE-
Advanced TDD is installed.
Setting measure setup
After configuring test parameters as described in the
“Configuring test parameters” on page 265, you
can continue your measurement. The measurement settings can be saved and recalled as a file. You
can also use JDViewer, PC application software to configure a measure setup, save as a file, and load
the file on to the instrument.
