Modulation Analysis (continued)
Subframe measures, with LTE and MBMS*, the data and con-
trol channel power and modulation quality in any subframe.
Frame measures, with LTE and MBMS*, the power and mod-
ulation quality for all data and control channels in a frame.
Time Alignment Error for LTE/MIMO measures the transmis-
sion time difference between Antenna 1 and Antenna 2 at eNodeB.
Data Allocation Map measures, with LTE and MBMS*, the
power level for all resource blocks across subframes and shows
data utilization within a frame.
Auto Measure performs with only one key press that lets users
easily and quickly check the RF and modulation parameters.
All base stations are uniformly tested with the same proce-
dure which provides virtually no errors due to test variability.
Additionally, this function reduced human errors which also
improve efficiency. Predefined tests allow users at all skill
levels, to obtain consistent and accurate results.
*Only available for the JD748A with MBMS enabled.
