To select the number of antenna ports, tap the MIMO and select 2x2 or 4x4.
To assign an antenna port number automatically or manually, tap Menu >
Antenna Port and select the options from Auto, Antenna 0, Antenna 1,
Antenna 2, or Antenna 3.
If the MIMO is set to 2x2, the antenna ports 2 and 3 are disabled.
To turn the Multimedia Broadcast Multicast Service (MBMS) feature on or off,
tap MBMS and select On or Off. For proper MBMS testing, you need to set
the Subframe Number in the upper right screen with the same PMCH
subframe number.
To set the Multicast Broadcast Single Frequency Network (MBSFN) detection
automatically or manually for MBMS testing, tap MBSFN and select Auto or
Manual.
An automatically detected or manually entered MBSFN ID appears on the
screen.
To select the Cyclic Prefix, tap Cyclic Prefix and select Normal or
Extended.
To set the threshold for PDSCH, tap PDSCH Threshold and enter a value by
using the on-screen keyboard.
Tap PDSCH Modulation Type, and then select the modulation type option:
Auto, QPSK, 16 QAM, 64 QAM, 256 QAM, E-TM3.3, E-TM3.2, E-TM3.1a,
E-TM3.1, E-TM2a, E-TM2, E-TM1.2 or E-TM1.1
If two or more modulation types are used in a frame, select Auto. If the
PDSCH uses the same modulation type in a frame or in a subframe, select a
specific modulation type to get more accurate EVM.
Tap PDSCH Precoding to set On or Off to enable or disable the PDSCH
precoding.
