6
Tap PCI and input a value from 0 to 503 using the on-screen keyboard.
The PCI switches to Manual.
7
Tap Antenna Port to assign an antenna port number automatically or manually,
and select 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.
8
Select MIMO between 2x2 and 4x4 to set the number of antenna ports.
9
Select Cyclic Prefix between Normal and Extended.
Cyclic prefix works as a buffer region or guard interval to protect the OFDM
signals from inter symbol interference.

Auto lets the instrument detect the Physical Cell ID for the DSS signal auto-
matically.
Manual sets the specific Physical Cell ID for the DSS signal manually in
order to speed up the synchronization with a BTS.
Normal: Intended to be sufficient for the majority of scenarios
Extended: Intended for scenarios with particularly high delay spread
