General Measurement Setups

Please refer to the User Guide for selecting the LTE Signal Analyzer mode, setting up frequency, amplitude, and file management. In addition, perform the following LTE specific setup procedures.

1.	Press the Setup main menu key.

2.	Press the BW submenu key to open the Select Bandwidth list. Select the desired Bandwidth with the arrow keys or rotary knob and press Enter.

Press the EVM Mode submenu key to select either Auto or PBCH Only. Selecting Auto measures Physical Downlink Shared Channel (PDSCH) if data is available, otherwise it measures Physical Broadcast Channel (PBCH), a control channel that carries a broadcast message. Selecting PBCH Only forces a PBCH measurement.


Note	The Constellation will show a QPSK constellation when PBCH is being measured. PBCH Only mode is especially useful when making measurements over the air under conditions where the transmitted data uses MIMO.

Press Sync then the Sync Type submenu key to select between the Normal (SS) or RS for synchronization. RS should be selected ONLY when there is no sync signal. This happens only when directly connected to a base station that is configured such that one of the antenna ports does not have a sync signal. When RS is selected, the Cell ID submenu key becomes active. Enter the Cell ID of the base station. The Cell ID field is automatically populated with the last measured Cell ID for user convenience.


Note	Sync Type RS is only supported when BW is set to 10 MHz.

5.	Press back to return to the Setup main menu.
