Interconnecting the Unidirectional MIMO (Baseband) Modules
Complete the following steps to connect the modules of the unidirectional MIMO (baseband)
mmWave Transceiver System configuration.
1.
Connect the adjoining PXIe-3630 and PXIe-7902 modules in the RX chassis using four
Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) cables.
a)
Connect the 0 connector of the PXIe-3630 front panel to the PORT 0 connector of
the PXIe-7902 front panel.
b)
Connect the 1 connector of the PXIe-3630 front panel to the PORT 1 connector of
the PXIe-7902 front panel.
c)
Connect the 2 connector of the PXIe-3630 front panel to the PORT 2 connector of
the PXIe-7902 front panel.
d)
Connect the 3 connector of the PXIe-3630 front panel to the PORT 3 connector of
the PXIe-7902 front panel.
