2. Mini-SAS HD(m)-to-Mini-SAS HD(m) (8.25 in.) Cables
6. Repeat steps 1 through 5 for the second RX/TX chassis.
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 Bidirectional MIMO (Baseband and IF)
Modules
Complete the following steps to connect the modules of the bidirectional MIMO (baseband
and IF) mmWave Transceiver System configuration.
1.
Connect the adjoining PXIe-3610 and PXIe-3620 modules using four MMPX(m)-to-
MMPX(m) cables.
a)
Connect the I+ connector of the PXIe-3610 front panel to the TX I+ connector of the
PXIe-3620 front panel.
b) Connect the I– connector of the PXIe-3610 front panel to the TX I– connector of the
PXIe-3620 front panel.
c) Connect the Q+ connector of the PXIe-3610 front panel to the TX Q+ connector of
the PXIe-3620 front panel.
d) Connect the Q– connector of the PXIe-3610 front panel to the TX Q– connector of
the PXIe-3620 front panel.
2. Connect the adjoining PXIe-3620 and PXIe-3630 modules 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.
