1. Verifying the System Requirements

To use an NI signal generator with NI-FGEN, your system must meet certain

requirements. For more information on minimum system, recommended

system, and supported application development environments (ADEs), refer

to the NI-FGEN Instrument Driver Readme, which is available on the

NI-FGEN CDs.

Note After you install NI-FGEN, you can access the

NI-FGEN Instrument Driver Readme at Start»All Programs»

National Instruments»NI-FGEN»Documentation.

NI SIgnal Generators Getting Started Guide 4 ni.com

2. Unpacking

NI signal generators ship in an antistatic envelope to prevent electrostatic

discharge (ESD). ESD can damage several components on the device.

Caution Never touch the exposed pins of connectors.

To avoid damage when handling the device, take the following precautions:

• Ground yourself using a grounding strap or by touching a grounded

object.

• Touch the antistatic package to a metal part of your computer chassis

before removing the device from the package.

Remove the device from the envelope and inspect it for loose components or

any sign of damage. Notify NI if the device appears damaged in any way.

Do not install a damaged device into your computer.

Store the device in the antistatic envelope when not in use.

3. Verifying the Kit Contents

The following items are included in the NI signal generator kit:

❑NI signal generator

❑SMB-BNC cable (NI 5404/5412/5421/5422/5441/5442 only)

❑NI-FGEN instrument driver DVD-sized case, which contains the

following items:

– NI-FGEN CDs, which include the NI Signal Generators Help

– NI Signal Generators Getting Started Guide

❑NI Analog Waveform Editor CD. Eligible hardware kits receive an

activation license. (NI 5412/5421/5422/5441/5442 only)

❑Other included documents:

– The specifications document for the NI signal generator

– Read Me First: Safety and Radio-Frequency Interference

–Maintain Forced-Air Cooling Note to Users (except the

NI 5401/5404/5411/5431 devices)

– Retrofitting Your PXI Module Note to Users

❑(NI 5431 only) NI Composite Video Generator CD

EMI Gasket

The NI signal generator kit may also include an EMI gasket and the

Retrofitting Your PXI Module Note to Users that describes under what

conditions you should install the gasket. Refer to the Installing PXI Modules

section for more information about when you should install the gasket.

Other Required Items

In addition to the items contained in the kit, you need the following items to

install your signal generator:

❑1/8 in. flathead screwdriver

❑Cables appropriate for use with your device

♦For PXI devices

• A PXI chassis, a PXI/SCXI combination chassis,

or a PXI/CompactPCI chassis and chassis documentation

• A PXI controller or MXI bridge

♦For PXI Express devices

• A PXI Express chassis and chassis documentation

• A PXI Express controller or a MXI-Express bridge

♦For PCI devices

• A desktop computer with its documentation

Note If your application uses NI-TClk synchronization, you must

use a RTSI cable to connect the devices (PCI DAQmx devices

only).

4. Installing the Software

The NI-FGEN CDs, included with your device, install the instrument driver

for all NI signal generators. NI-FGEN CDs also include the FGEN Soft Front

Panel (SFP), which is an easy, interactive tool that helps you quickly begin

working with the NI signal generator.

To install NI-FGEN, complete the following steps:

1. (Optional) If you are developing an application for the NI signal

generator, install an ADE, such as LabVIEW or LabWindows™/CVI™.

2. Insert the first CD of the NI-FGEN CD set. The NI-FGEN installer

should open automatically.

Note If the installation window does not appear, navigate to the

CD drive, double-click the drive, and double-click setup.exe.

NI SIgnal Generators Getting Started Guide 6 ni.com

3. Follow the instructions in the installation prompts. For installation

troubleshooting information contact NI technical support or visit

ni.com/support.

(Windows Vista) Users may see access and security messages during

installation. Accept the prompts to complete the installation.

4. When the installer completes, a dialog box appears that asks if you want

to restart, shut down, or restart later. Select Restart.

5. If you are using a system running the LabVIEW Real-Time Module,

download NI-FGEN to the target using Measurement & Automation

Explorer (MAX). Refer to the Measurement & Automation Explorer

Remote Systems Help by selecting Help»Help Topics»Remote Systems

in MAX.

(NI 5431 only) Insert the NI Composite Video Generator CD into the

CD drive and follow the instructions in the installation window.

5. Installing the Hardware

Caution You must power off and unplug the computer or chassis

before installing the device.

To prevent damage to the device caused by ESD or contamination,

handle the device using the edges or the metal bracket. Refer to the

Read Me First: Safety and Radio-Frequency Interference document

for more information about handling your device.

Note You must install the NI-FGEN software before installing the

hardware.

Cooling Considerations for PXI and PCI Devices

Caution When installing an NI-DAQmx device (except the

NI 5404), follow the guidelines in the Maintain Forced-Air Cooling

Note to Users document included in the kit to ensure that the device

is cooled effectively.

Thermal Shutdown—If the device temperature rises above the maximum

operating temperature, the device shuts down and MAX or NI-FGEN

notifies you with an error message. For information about the operating

temperatures for your device, refer to the device specifications. To

re-enable the device after thermal shutdown, you must perform a hard reset,

using one of the following methods:

• Power off the computer or chassis that contains the device. After the

device has cooled, power on the computer or chassis and reboot the

controller, if necessary.

• Call the niFgen Reset Device VI or the niFgen_ResetDevice function.

• Perform a device reset in MAX. For more information about resetting a

device in MAX, refer to MAX Help for NI-DAQmx by navigating to

Help»Help Topics»NI-DAQmx»MAX Help for NI-DAQmx

within MAX.

Review the guidelines in the Maintain Forced-Air Cooling Note to Users

and make any necessary adjustments. The thermal shutdown error is reported

until the device has cooled to an acceptable operating temperature and has

been reset successfully.

Installing PXI Modules

To install the device in either a PXI chassis, a PXI/SCXI combination chassis,

or a PXI/CompactPCI chassis, complete the following steps:

1. Power off and unplug the PXI chassis.

2. (Optional) If you need to use the provided EMI gasket to reduce

high-frequency emissions, install it now. Refer to the Retrofitting Your

PXI Module Note to Users for more information about installing the

gasket.

3. Position the PXI chassis so that inlet and outlet vents are not obstructed.

For more information, refer to the chassis documentation.

4. Make sure that the ejector handle is in the unlatched (downward)

position.

5. Hold the PXI module by the ejector handle and slide it into an empty slot.

Make sure that the base engages with the guides in the chassis, as shown

in Figure 1.

NI SIgnal Generators Getting Started Guide 8 ni.com

Figure 1. PXI Installation

6. Slide the module completely into the chassis and latch it by pulling up on

the ejector handle. Tighten the captive screws at the top and bottom of

the module front panel.

Caution Performance may suffer if both screws are not tightened

properly.

7. Verify that the PXI chassis fans are operable and free of dust and other

contaminants restricting airflow. Refer to the Cooling Considerations for

PXI and PCI Devices section for more information.

8. Plug in the PXI chassis.

Uninstalling PXI Modules

When removing PXI modules from the chassis, ensure that you are grounded

with a grounding strap or are touching a grounded metal surface. To avoid

ESD, do not touch the exposed connector pins or any exposed circuitry on

the device. When not in use, PXI devices should be stored in the original

antistatic envelope to avoid damage.

Hot Surface During operation, the metal surfaces of PXI devices

may become hot. Be careful when removing the device from the

chassis or when moving it to a different peripheral slot. When

removing the device, hold it by only the ejector handle and front

panel.
