Installing the NI 5668R
Caution To prevent damage to the NI 5668R caused by ESD or contamination,
handle the module using the edges or the metal bracket.
You must install NI-RFSA before installing the hardware.
Before you install the hardware, refer to the guidelines in the Maintain Forced-Air Cooling
Note to Users included with the module to ensure that the device can cool itself effectively.
To use the included cables, you must install the NI 5624R IF digitizer immediately to the left
of the NI 5606 RF downconverter module, and you must install the NI 5653 LO source
module immediately to the right of the NI 5606 RF downconverter module.
1. Ensure the AC power source is connected to the chassis before installing the module.
The AC power cord grounds the chassis and protects it from electrical damage while you
install the module.
2. Power off the chassis.
3. Inspect the slot pins on the chassis backplane for any bends or damage prior to
installation. Do not install a module if the backplane is damaged.
4. Remove the black plastic covers from all the captive screws on the module front panel.
5. Identify a supported slot in the chassis. The following figure shows the symbols that
indicate the slot types.

4. Install a 50 Ω load on each of the NI 5606 module LO1 OUT, LO3 OUT, and
IF IN / BIAS OUT connectors.
NI PXIe-5668R Getting Started Guide | © National Instruments | 9

5. 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.
Note If the SMA cable does not exactly align with the SMA connector, bend
the cable slightly by hand to align the cable and the connector. The amount of
bending should be minimal. The cables can be damaged by excessive bending.
6. 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 damage device connectors,
degrade signal fidelity and phase locked loop performance, or 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.
7. Power on your PXI Express chassis and controller system. If you are using a MXI device
and a remote controller, ensure that the chassis is powered on prior to triggering the
remote controller. Using the controller system before the chassis is powered on may
cause installed devices to not appear in MAX.
8. Verify that the ACCESS LED is on for all three modules.

Troubleshooting on page 26
If an issue persists after you complete a troubleshooting procedure, contact NI technical
support or visit ni.com/support.
Refer to the NI RF Vector Signal Analyzers Help for information about how to make
connections using an external clock, or how to connect multiple NI 5668R modules.
Direct Connections to the NI 5606
The NI 5606 is a precision RF instrument that is sensitive to ESD and transients. Ensure you
are making proper direct connections to the NI 5606 to avoid damaging the device.
Caution Apply external signals only while the NI 5606 is powered on. Applying
external signals while the device is powered off may cause damage.
• Ensure you are properly grounded when manipulating cables or antennas connected to the
NI 5606 RF IN connector.
• If you are using noninsulated devices, such as an RF antenna, ensure the devices are
maintained in a static-free environment.
• If you are using an active device, such as a preamplifier or switch routed to the NI 5606
RF IN connector, ensure that the device cannot generate signal transients greater than the
RF and DC specifications of the NI 5606 RF IN connector.

Refer to the user documentation for required maintenance measures to ensure user
safety and/or preserve the specified EMC performance.
The signal pins of this product's input/output ports can be damaged if subjected to
ESD. To prevent damage, turn off power to the product before connecting cables and
employ industry-standard ESD prevention measures during installation, maintenance,

NI PXIe-5668R Getting Started Guide | © National Instruments | 11

Table 3. NI 5606 RF Downconverter Front Panel Connectors
Connector Use
RF IN Connects to the analog RF input signal to be measured by the vector signal
analyzer. The maximum RF input is +30 dBm.
Note The NI 5606 downconverter module has no internal DC
block. High-frequency components in the NI 5606 can be
damaged when DC signals are applied directly to the RF IN
connector. The NI 5606 ships with a 2.92 mm DC block
attached to the RF IN connector to prevent damage to the device
when a DC input signal is present. The DC block must be
removed to make measurements below 16 kHz. NI recommends
that you keep the DC block attached to the RF IN connector for
all measurements at frequencies greater than or equal to 16 kHz
to maximize the accuracy of the device. To prevent damage to
the downconverter, ensure that the DC voltage at the RF IN
connector is between -2 VDC and +2 VDC. With the DC block
removed, the maximum allowed voltage is 0 VDC.
Caution To reinstall the DC block on the NI 5606 RF IN
connector, use a torque wrench set to a maximum torque of
1.65 N · m (15 lb · in.). Using more than the recommended
amount of torque may damage the RF IN connector.
IF OUT Connects to the IF IN connector on the NI 5624R module front panel.
This connector is the output terminal for the frequency-translated IF signal.
LO1 IN Connects to the LO1 OUT connector on the NI 5653 module front panel.
This connector is the input terminal for the LO1 (3.2 GHz to 8.3 GHz)
source. LO1 IN is an SMA connector with an impedance of 50 Ω
(nominal).
LO2 IN Connects to the LO2 OUT connector on the NI 5653 module front panel.
This connector is the input terminal for the LO2 (4 GHz) source. LO2 IN is
an SMA connector with an impedance of 50 Ω (nominal).
LO3 IN Connects to the LO3 OUT connector on the NI 5653 module front panel.
This connector is the input terminal for the LO3 (800 MHz) source. LO3
IN is an SMA connector with an impedance of 50 Ω (nominal).
