Test setup with R&S SMW and 6xR&S SGT
This test setup is a logical extension of the 1x4x4 test case.
Follow the instructions provided in the sections listed below but connect six R&S SGT
instruments instead:
1. Connect all 8 instruments to a LAN.
2. Connect the six R&S SGT to the HS DIG I/Q interfaces of the R&S SMW
(see Figure 3-19 for explanation of the principle)
3. Distribute the internal reference frequency of R&S SMW to the other instruments.
Connect the instruments in a daisy chain.
4. Perform the configurations described in:
● Chapter 3.9.3, "How to Define the MIMO Scenario", on page 193
● Chapter 3.9.4, "How to Route the I/Q Streams to the Output Interfaces",
on page 196
● "To connect instruments to the I/Q digital interface" on page 202
5. If the test setup requires a beamformed signal, couple the local oscillators (LO)
of all instruments:
● Activate the local oscillator of the R&S SMW.
● Distribute the LO signal to the other instruments (instead of the reference fre-
quency):
