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.

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

loop (PLL) lock errors. The NI PXIe-6674T Timing and Multichassis
Synchronization module is an option for synchronizing multiple digitizer
clocks. The NI 6674T 10 MHz clock can be driven onto the PXI backplane
when placed in the chassis System Timing Slot, also known as the Star
Trigger Controller Slot. You can also connect the output of the NI 6674T
10 MHz clock to the 10 MHz BNC IN terminal on the back of the PXI chassis
from any PXI chassis slot using an SMA-to-BNC cable.

2. Using the flexible SMA-to-SMA cable, connect the REF OUT 100 MHz connector
on the NI 5653 front panel to the CLK IN connector on the NI 5622 front panel.
3. Using the short semi-rigid SMA-to-SMA cable (labeled K), connect the IF OUT
connector on the NI 5603 front panel to the IF IN connector on the NI 5622
front panel.
4. Hand-tighten all SMA cable ends on the SMA connectors aer the cable center
pins are correctly aligned and connected. The cable connectors should tighten
without much torque or eort. If a cable bends due to incorrect alignment,
remove the cable from the front panel connector and reconnect the cable
center pin on the SMA cable to the SMA connector.
5. Carefully complete tightening all SMA connectors to 1 N · m using an
appropriate torque wrench (not included) or torque screwdriver and SMA
driver bit. Tighten only until the wrench clicks.
Caution Incorrect torque at SMA connections can degrade signal
fidelity and phase-locked loop (PLL) performance and may cause
insertion loss. Use an appropriate torque wrench or torque
screwdriver and SMA driver bit to ensure all SMA connections are
properly torqued. SMA connectors for connections to external
equipment may require torque dierent from 1 N · m, depending on
the connector type, material, and manufacturer.
Interconnecting the Slave NI 5665 Modules
The NI 5665 MIMO test system includes the following cables to interconnect
additional modules:

NI 5622 front panel.
2. Using the flexible SMA-to-SMA cable, connect the CLK OUT connector from the

Configuring the NI 5665 in MAX
Use Measurement & Automation Explorer (MAX) to configure your National
Instruments hardware. MAX informs other programs about which devices reside in
the system and how they are configured. MAX is automatically installed with
NI-RFSA.
1. Launch MAX.
2. In the configuration tree, double-click Devices and Interfaces to see the list of
installed devices.
Installed devices appear under the name of their associated chassis.
3. Expand your Chassis tree item.
MAX lists all devices installed in the chassis. Your default device names may
vary.
Note If you do not see your device listed, press <F5> to refresh the
list of installed devices. If the device is still not listed, power o the
system, ensure the device is correctly installed, and restart.
4. Record the device identifier MAX assigns to the hardware. Use this identifier
when programming the NI 5665.
5. Associate the hardware modules that comprise the master and slave NI 5665.
© National Instruments 9
PXIe-5665 3.6 GHz Getting Started

1. Select the master NI 5603 module that is identified as not configured in
the configuration tree.
2. In the Associated Devices section, select the appropriate module from
each system component drop-down listbox.
For the master NI 5665, you must associate the NI 5622 IF digitizer
module and the NI 5653 LO source module.
3. Select the slave NI 5603 module that is identified as not configured in
the configuration tree.
4. In the Associated Devices section, select the appropriate module from
each system component drop-down listbox.
For the slave NI 5665, you must associated the NI 5622 IF digitizer
module and you must select External as the LO source for each slave
device because the LO signals are shared by all NI 5665 devices.
5. Click Save in the MAX toolbar.
Note Module associations may be lost when you move the modules
to dierent chassis slots.
6. Self-test the device modules by selecting the modules in the configuration
tree, and clicking Self-Test in the MAX toolbar. Repeat this step for all
modules in your NI 5665 system.
The MAX self-test performs a basic verification of hardware resources.
Where Do I Go from Here?
Now that you have installed your hardware, interconnected the modules, and
configured the modules in MAX, you can begin programming your hardware using
the NI-RFSA instrument driver.
