e)
If you have a MIMO system, repeat steps a through d for the second PXIe-3620
module in the RX chassis and a second mmRH-3652/3653.
2.
Connect the TX chassis to the mmRH-3642/3643.
a)
Connect the DIGITAL I/O connector of the PXIe-3620 front panel in the TX chassis
to the DIO adapter module using an EPLSP cable.
b)
Connect the DIO adapter module to the DIO 1 connector
2
of the mmRH-3642/3643
back panel using an HDMI(m)-to-mini-HDMI(m) cable.
c)
Connect the TX LO1 connector of the PXIe-3620 front panel in the TX chassis to
the LO IN TX connector of the mmRH-3642/3643 back panel using an SMA(m)-to-
SMA(m) cable.
2
You may connect the DIO adapter module to the DIO 0 connector instead of the DIO 1 connector.
The choice of connector does not affect results.
