Measurements > Modulation
Power vs Resource Block: Press once to display the Power vs. Resource
Block measurement window. Press again to open the “Power vs. Resource
Block Menu” on page 6-39 for setting up the Resource Block Color Map
parameters.
Constellation: Press this submenu key to set the modulation measurement
to Constellation view. This view displays the constellation of the modulated
data symbols over subframe 0. Press the key again to open the
“Constellation Menu” on page 6-40 .
Control Channel Power: Press the Control Channel Power submenu key to
set the display as bar graph or table. Refer to the “Control Channel Power
Menu” on page 6-41 .
Tx Time Alignment: Press to set the modulation measurement to Tx Time
Alignment view. Refer to “Tx Time Alignment” on page 6-15 .
Modulation Summary: Press this submenu key to display a summary table
of all the modulation-related measurement results:
Ref Signal (RS) Power
Sync Signal (SS) Power
EVM (rms)
EVM(QPSK)
EVM(16-QAM)
EVM(64-QAM)
EVM(256-QAM)
Freq Error
Freq Error (ppm)
Cell ID
PBCH Power
Note: 256-QAM modulation scheme is supported only when
Option 886 is installed.
Back: Press this submenu key to return to “Measurements Menu” on
