Data channel
The Data Channel measures the constellation for the specified resource block as well
as the modulation accuracy of each PDSCH at the specified subframe.

NOTE
For MBMS testing, this subframe number must be either 0 nor 5 as these
subframes 0 and 5 are not available for MBMS and it must be set to the MBMS
transmitted channel's subframe number.
Auto lets the instrument detect the Physical Cell ID for the LTE signal auto-
matically.
Manual sets a specific Physical Cell ID for the LTE signal manually in order to
speed up with the synchronization with a BTS.
