GETTING STARTED GUIDE
NI PXIe-5665 3.6 GHz
Vector Signal Analyzer
MIMO Platform
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,
software, 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 left 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 left 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.

1. Using the three medium semi-rigid SMA-to-SMA cables (labeled J), connect the LO1,
LO2, and LO3 connectors on the NI 5653 front panel to the associated LO1 IN, LO2 IN,
and LO3 IN connectors on the NI 5603 front panel.
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 after the cable center pins are
correctly aligned and connected. The cable connectors should tighten without much
torque or effort. 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 different 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:
• Semi-rigid SMA-to-SMA cable (labeled M), (x3)
• Short, semi-rigid SMA-to-SMA cable (labeled K)
• Flexible SMA-to-SMA cable

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.
Note If you are using the NI 5665 with the LabVIEW Real-Time Module,
expand Remote Systems. Find your target IP address or name, expand it, and
then expand Devices and Interfaces.
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 off 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.
a) Select the master NI 5603 module that is identified as not configured in the
configuration tree.
b) In the Associated Devices section, select the appropriate module from each system
component drop-down listbox.
6| ni.com | NI PXIe-5665 3.6 GHz Vector Signal Analyzer MIMO Platform Getting Started Guide

For the master NI 5665, you must associate the NI 5622 IF digitizer module and the
NI 5653 LO source module.
c) Select the slave NI 5603 module that is identified as not configured in the
configuration tree.
d) 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.
e) Click Save in the MAX toolbar.
Note Module associations may be lost when you move the modules to
different 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.
