Bidirectional System Setup
This section describes how to connect the modules of a bidirectional mmWave Transceiver
System.
Bidirectional mmWave Transceiver System configurations are as follows:
•
Bidirectional SISO (baseband)
•
Bidirectional SISO (baseband and IF)
•
Bidirectional MIMO (baseband)
•
Bidirectional MIMO (baseband and IF)
Each configuration consists of two RX/TX chassis with identical module configurations.
Interconnecting the Bidirectional SISO (Baseband) Modules
Complete the following steps to connect the modules of the bidirectional SISO (baseband)
mmWave Transceiver System configuration.
1.
Connect the adjoining PXIe-7902 and PXIe-3610 modules using four Mini-SAS HD(m)-
to-Mini-SAS HD(m) (8.25 in.) cables.
a)
Connect the PORT 0 connector of the PXIe-7902 front panel to the 0 connector of
the PXIe-3610 front panel.
