Data Allocation Map measurement with LTE/LTE-A TDD Analyzer
Carrier Aggregation
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 CA5G provides carrier aggregation measurements supporting for all the different modes with carrier aggregation bands added
to the channel standard.
Setting measure setup
After configuring spectrum measurement in " Configuring Spectrum Measurements ", you can set the measure setup to continue your
measurement. The measurement settings can be saved and recalled as a file by selecting File Type as Setup and load the file onto
the instrument using the
Save/Load icons on the side bar.
1 Tap the Setup ( )icon on the side bar.
2 Tap CA Configuration or tap the Configuration ( ) icon then the component carrier configuration window appears.
3 Select the number of the component carrier to be set between one and five by tapping the number in Range box.
4 Set the Range On to set parameters and view the results for the selected component carrier on the screen or Off to turn it off.
5 Tap LAA (License Assisted Access) and select one among the three options: 2.4 GHz , 5 GHz , or Off .
6 Set the following parameters as needed: Center Frequency , Channel No , Bandwidth , Physical Cell ID , MBMS , MBSFN ,
MIMO , Antenna Port , CFI, PHICH Ng , Cyclic Prefix , and PDSCH Modulation Type .
7 Tap EVM Detection Mode and select Single
or
Combine .
▪
Single: Testing on one single antenna connected to your CA5G series with a cable
▪
Combine: Testing on multiple antennas connected to your CA5G series with a 2x1 or 4x1 combiner or an antenna
8 To select the subframe number to be measured, do one of the following:
▪
If the EVM Detection Mode is set to Single , tap Subframe Number and set the subframe number
▪
If the EVM Detection Mode is set to Combine , tap Subframe Number, and then select 0 or 5
9 To set the threshold for PDSCH, tap PDSCH Threshold and enter a value by using the on-screen keyboard.
