1. Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) Cables
Disconnect cables or otherwise attenuate the signal to ensure that no signal is entering the
baseband ports on the PXIe-3630 module during system startup.

Interconnecting the Unidirectional MIMO (Baseband and IF)
Modules
Complete the following steps to connect the modules of the unidirectional MIMO (baseband
and IF) mmWave Transceiver System configuration.
1.
Connect one set of adjoining PXIe-3620 and PXIe-3630 modules in the RX chassis using
four MMPX(m)-to-MMPX(m) cables.
a)
Connect the RX I+ connector of the PXIe-3620 front panel to the I+ connector of the
PXIe-3630 front panel.
b)
Connect the RX I– connector of the PXIe-3620 front panel to the I– connector of the
PXIe-3630 front panel.
c)
Connect the RX Q+ connector of the PXIe-3620 front panel to the Q+ connector of
the PXIe-3630 front panel.
d)
Connect the RX Q– connector of the PXIe-3620 front panel to the Q– connector of
the PXIe-3630 front panel.
2.
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.
