NI PXIe-5665 3.6 GHz MIMO Getting Started
Guide
This document describes the proper slot placement and module connections
needed for a phase-coherent multiple input, multiple output (MIMO) system with
the NI PXIe-5665 3.6 GHz (NI 5665) vector signal analyzer (VSA).
The NI 5665 comprises the following modules:
■ NI PXIe-5603 (NI 5603) RF downconverter
■ NI PXIe-5653 (NI 5653) LO module
■ NI PXIe-5622 (NI 5622) IF digitizer
Preconfigured NI MIMO test systems that include these modules, a chassis,
controller, soware, and accessories are available for purchase at ni.com/mimo.
This document also describes how to correctly configure the devices in
Measurement & Automation Explorer (MAX) and how to associate the modules.
Refer to the NI PXIe-5665 Getting Started Guide and the NI PXIe-5665
Specifications, available at ni.com/manuals, for more information about device
specifications, maintenance, and safety information.
Note The master NI 5665 is the RF signal analyzer that receives the LO
signal directly from the NI 5653 module. Slave NI 5665 devices refer to the
additional analyzer channels that receive daisy-chained LO and Reference
Clock signals.
Installing the Modules
The NI 5665 MIMO test system equipment setup requires you to install a master
NI 5665 and additional NI 5665 slave devices in your PXI Express chassis.
Note The following installation instructions use semi-rigid cables when
making some module connections. The semi-rigid cables restrict slot

placement because they require you to place certain modules next to each
other in the chassis.
1. Install the NI 5665 master device in your chassis. To use the cables included
with your module kit, install the NI 5622 IF digitizer module immediately to
the le of the NI 5603 RF downconverter module, and install the NI 5653 LO
module immediately to the right of the NI 5603.
The following figure illustrates the correct placement of the three modules
that comprise the NI 5665.
Tip Install the master NI 5665 modules in the chassis with enough
room to install your slave NI 5665 devices to the le of the master
device.

2. Install the slave NI 5665 device in your chassis to the le of the master NI 5665
device. You can install multiple NI 5665 devices to the le of the master
NI 5665, depending on your application requirements.

Interconnecting the Modules
This section describes how to interconnect the master NI 5665 modules and how to
connect the slave NI 5665 modules to the master NI 5665 modules.
Note This module configuration frequency-locks to the NI 5653 100 MHz
onboard Reference Clock by daisy chaining the 100 MHz Reference Clock to
slave digitizer modules. To frequency-lock to the PXI backplane, the
NI 5653 requires an OCXO-quality timebase source present on the PXI
backplane.
For the best long-term phase stability over temperature, use the PXI
backplane as the Reference Clock source, but override the native PXI
chassis backplane clock with an OCXO-quality timebase that meets the
requirements listed in the NI PXIe-5665 Specifications. The NI 5665
cannot lock to the native PXI chassis backplane clock, and attempting to
do so without overriding it with an OCXO timebase results in phase-locked
