AT-1120 User Guide and Specifications

The AT-1120 is a one-channel, 2 GS/s, 14-bit, 800 MHz Analog Bandwidth, High-Speed Signal

Generator adapter module designed to work in conjunction with your NI FlexRIO™

FPGA module.

This document contains signal information and specifications for the AT-1120R, which is composed of

an NI FlexRIO FPGA module and the AT-1120. This document contains tutorial sections that

demonstrate how to generate signals using a LabVIEW FPGA example VI and how to create and run

your own LabVIEW project with the AT-1120R.

Note

Before configuring your AT-1120, you must install the appropriate software and

hardware. Refer to the NI FlexRIO FPGA Module Installation Guide and Specifications for

installation instructions. Figure 1 shows an example of a properly connected NI FlexRIO

device.

Figure 1. NI FlexRIO Device

Note

AT-1120R refers to the combination of your AT-1120 adapter module and your NI

FlexRIO FPGA module. AT-1120 refers to your AT-1120 adapter module only.

WARNING:

NI-7965R cannot be used

with AT-1120. It is recommended to use the NI-

7966R instead.

WARNING:

LabVIEW 2012 must be used with AT-1120 adapter module.

Electromagnetic Compatibility Guidelines

This product was tested and complies with the regulatory requirements and limits for electromagnetic

compatibility (EMC) as stated in the product specifications. These requirements and limits are designed

to provide reasonable protection against harmful interference when the product is operated in its

intended operational electromagnetic environment.

This product is intended for use in industrial locations. There is no guarantee that harmful

interference will not occur in a particular installation, when the product is connected to a test object, or

if the product is used in residential areas. To minimize the potential for the product to cause

interference to radio and television reception or to experience unacceptable performance

degradation, install and use this product in strict accordance with instructions in the product

documentation.

Furthermore, any changes or modifications to the product not expressly approved by Active

Technologies could void your authority to operate it under your local regulatory rules.

Caution

To ensure the specified EMC performance, you must install PXI EMC Filler Panels (National

Instruments part number 778700-01) in adjacent chassis slots. For more information about installing

PXI EMC filler panels on your NI 5762R, refer to the Appendix: Installing EMI Controls section of this

document.

Caution

To ensure the specified EMC performance, operate this product only with shielded cables

and accessories.

Caution

This product is sensitive to electrostatic discharge (ESD).

AT-1120 Component-Level Intellectual Property (CLIP)

The LabVIEW FPGA Module includes a feature for HDL IP integration called CLIP. NI FlexRIO devices

support two types of CLIP: user-defined and socketed.

•User-defined CLIP allows users to insert HDL IP into an FPGA target, enabling VHDL code to

communicate directly with an FPGA VI.

•Socketed CLIP provides the same IP integration functionality of the user-defined CLIP, but it also

allows the CLIP to communicate directly with circuitry external to the FPGA. Adapter module socketed

CLIP allows your IP to communicate directly with both the FPGA VI and the external adapter module

connector interface.

Figure 4 shows the relationship between an FPGA VI and CLIP.
