install it now. Refer to the Retrofitting Your PXI Module Note to Users

for gasket installation instructions.

5. Remove the packaging material on the PXI connector and on the screws.

6. Ensure that the ejector handle is in the unlatched (downward) position,

as shown in Figure 1.

7. Holding the module by the ejector handle, slide it into an empty slot,

ensuring that the base card (on the left when looking at the front of the

module) engages with the card guides in the chassis.

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

the ejector handle.

9. Tighten the captive screws at the top and bottom of the module front panel.

10. Before operating the module, install all chassis covers and filler panels.

Missing filler panels disrupt the necessary air circulation in the chassis.

Note NI recommends that you install slot blockers between

modules to maximize air flow. NI recommends using the PXI

Chassis Slot Blocker Kit, part number 778678-01, available for

purchase at ni.com.

11. Plug in and power on the chassis.

NI PXI modules are sensitive instruments that should be handled carefully.

Do not expose the module to temperatures or humidity beyond the rated

maximums. Keep the module free of dust by cleaning with compressed air

only. Do not clean the module with any solvents or liquids. For more

information about module cooling, refer to the guidelines in the Maintain

Forced-Air Cooling Note to Users included with your NI digital waveform

generator/analyzer.

Maintaining PXI Systems

Clean the fan filters on the chassis regularly to prevent air circulation path

blockage. Cleaning frequency depends on the amount of use and the

operating environment. For specific information about cleaning procedures,

and other recommended maintenance, refer to the module specifications and

the chassis user documentation.

Uninstalling PXI Modules

When removing PXI modules from the chassis, first power down the chassis.

Then ensure that you are grounded with a grounding strap or are touching a

grounded metal surface. To avoid ESD, do not touch the exposed pins of the

PXI connector or any exposed circuitry on the module. When not in use, PXI

modules should be stored in the original antistatic packaging to avoid

damage.

Hot Surface During operation, the metal surfaces of PXI modules

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

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

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

panel.

Installing a PCI Device

To install your PCI device, complete the following steps:

1. Power off and unplug the PC.

2. If the PC has multiple fan speed settings, ensure that the fans are set to

the highest setting.

3. Remove the PC cover.

4. Insert the device into an open PCI slot, as shown in Figure 2.

Figure 2. PCI Installation

NI recommends either leaving the slot adjacent to the fan side of the

device empty or using lower-profile devices in the slot adjacent to the

fan side.

NI Digital Waveform Generator/Analyzer Guide 10 ni.com

Caution It is important to completely screw the device into the PCI

slot, both for mechanical stability and for creating a solid ground

connection, which reduces signal noise. Some computer

manufacturers use a plastic securing lever to secure PCI devices;

such a lever is unacceptable and must be removed, or you must use

a different chassis. Improperly secured devices may affect the

accuracy of device specifications.

6. Before operating the device, install all filler panels. Missing filler panels

disrupt the necessary air circulation in the PC.

7. Replace the PC cover.

8. Plug in and power on the PC.

Maintaining PCI Systems

Inspect the onboard fan on a regular basis to prevent fan and air circulation

path blockage. Cleaning frequency depends on the amount of use and the

operating environment.

6. Configuring and Testing in MAX

To configure and test the NI digital waveform generator/analyzer in MAX,

complete the following steps:

1. Launch MAX to configure and test the digital waveform

generator/analyzer. MAX should automatically detect the device

you installed.

2. Expand Devices and Interfaces.

If you are using an NI digital waveform generator/analyzer with the

LabVIEW Real-Time Module, expand Remote Systems. Find your

target IP address or name, expand it, and then expand Devices and

Interfaces.

3. Expand NI-DAQmx Devices.

4. Check that your device appears under NI-DAQmx Devices.

Note If your device does not appear under NI-DAQmx Devices,

MAX did not detect the device, so you might need to refresh MAX

by selecting File»Refresh from the MAX menu or pressing <F5>.

5. You can perform a self-test on devices listed under NI-DAQmx Devices.

The self-test ensures that the device is installed correctly and can

communicate with NI-HSDIO. To perform a self-test, complete the
