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.
Auto lets the instrument set the number of OFDM symbols used for transmit-
ting PDCCHs in a subframe.
Manual sets the number of OFDM symbols manually.
NOTE
The set of OFDM symbols that can be used for PDCCH in a subframe is given
by 0, 2, 3 or 4 in 1.4 MHz bandwidth and 1, 2 or 3 in another bandwidth.
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

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:
