2 Hardware setup
2.1 Power supply
Plug the external power cable provided with the Simbox in the AC-in Connector and place the
toggle switch located in the rear panel on position "1", then press the Power on button on the
top of the front panel to turn the system on.
The led will light up blue once Simbox is powered ON .
Power adapter specifications:
Input: 100~240 V AC, 50~60 Hz
2.2 RF connection
Before initiating any testing with the LTE UE simulator, first thing to do is to connect it
correctly to the eNodeB/gNodeB.
Your setup is composed of four SDR cards that have two RX, two TX plus one GPS SMA
connectors.
• RX1 is the main receive antenna port. Must be connected to eNodeB/gNodeB main transmit
antenna
• RX2 is the diversity receive antenna port. It is needed when diversity or MIMO transmission
modes are used. Must be connected to eNodeB/gNodeB secondary transmit (Diversity)
antenna
• TX1 is the main transmit antenna port. Must be connected to eNodeB/gNodeB main receive
antenna
• TX2 is not used. (the current version only supports a single uplink antenna)
• GPS is used for connecting an external GPS clock. See trx sdr.pdf file for more details.
Each SDR card can support one cell MIMO 2x2. By consequence, for scenarios such as
MIMO 4x4 or multiple cells, several SDR cards are required. See [4x4 MIMO RF connection],
page 6, or See [multiple cells RF connection], page 3, for more details.
LTE UE simulator can be connected to the eNodeB either using RF cables or in wireless way
using LTE antennas.
• When LTE antennas are used, RF connection is simple and just consist in connecting the
four antennas provided to TX1,TX2,RX1 and RX2 SMA connectors.
