thing you read. Its purpose is to guide you through setting up the

digital waveform generator/analyzer module and configuring it to

generate or acquire your first samples.

• Help—This online document provides more in-depth information

about the hardware capabilities of the digital waveform

generator/analyzer module, theory of operation discussion, and

information on programming flow and software reference.

• Specifications—This printed document provides specifications for the

NI hardware.

Visit ni.com/manuals for the most current documentation.

You also may have documentation for any application development

environment (ADE) you are using.

Installing Cables

A cable connects the NI CB-2162 to the digital waveform

generator/analyzer. Figure 2 shows how to install a cable.

Figure 2. Connecting a 68-Pin Digital Waveform Generator/Analyzer to the CB-2162

Refer to Figure 2 as you complete the following steps to install the

supported cable:

Caution Before connecting the cable, disconnect power from the module, accessory, and

any other connected hardware to prevent damage to the hardware and personal injury. NI is

not liable for damage resulting from improper connections.

1. Install NI-HSDIO or NI-DAQmx and the digital waveform

generator/analyzer by following the installation procedure in the

Getting Started Guide that shipped with your device.

Caution Before attaching any cables or accessories, install the digital waveform

generator/analyzer. Refer to the Getting Started Guide that shipped with your device for

instructions on installing the module.

2. Attach either end of the cable assembly to the DDC connector of the

digital waveform generator/analyzer module and secure the cable with

the captive screws on the cable connector.

3. Attach the other end of the cable assembly to the DDC connector of the

NI CB-2162 and secure them together with the captive screws on the

cable connector.

Connecting Signals

Each DIO, PFI, and clock channel of the digital waveform

generator/analyzer connects to a corresponding pin on the NI CB-2162.

Refer to Figure 1 for the location of these pins on the NI CB-2162.

Caution Before powering down the digital waveform generator/analyzer module, remove

power from the prototyping area of the NI CB-2162. NI is not liable for any damage

resulting from improper signal connections.

Note Refer to the help file for your device for information about the number of available

DIO channels on your device. DIO <20..31> or PFI_0 may not be applicable to your

device. The function of DDC CLK OUT/PFI_4 and STROBE/PFI_5 may be unique to

your device.

Table 1 describes the DDC signals shown in Figure 3.

The NI CB-2162 provides connectivity to up to 32 of the single-ended

DIO channels of an NI digital waveform generator/analyzer. The 32 DIO

channels are divided into two bundles of 16 × 2 header pins. Each bundle

is grouped by signal and ground pairs. The ground pins provide ground

return paths for the DIO channels.

You can make connections to the DIO channels, the PFI channels,

DDC CLK OUT/PFI_4, or STROBE/PFI_5 on the NI CB-2162 using a

1 × 2 header receptacle, ribbon cable, a wire-wrap technique, or by

soldering directly to the pins. Examples of how to make these connections

are provided in the following sections.

Caution Connections that exceed any of the maximum ratings for the NI CB-2162 or the

NI digital waveform generator/analyzer module can damage the module and the computer.

Maximum input ratings are provided in the Specifications section and in the specifications

document that shipped with the digital waveform generator/analyzer. NI is not liable for

any damage resulting from such signal connections.

GND Ground reference for signals.

RESERVED These channels are reserved for system use.

Do not connect signals to these channels.

*Refer to your device documentation for support.

Using 1 × 2 Header Receptacles

Each signal and ground header pair is labeled on the NI CB-2162 and in

Figure 1. These header pairs are arranged so that you can make quick

connections using a 1 × 2 header receptacle to a coaxial cable assembly.

Note Header receptacle assemblies are not included with the NI CB-2162, but you can

create custom assemblies by purchasing parts from vendors such as 3M.

Connectivity is made by inserting the receptacle onto the appropriate

header pair. Refer to the receptacle documentation to assure that proper

connections are made to signal and ground.

Figure 4 shows how to make 1 × 2 header receptacle connections.

Using a Ribbon Cable

The header pairs on the NI CB-2162 are available for single wire probing.

You also can use 32-pin ribbon cables to easily connect a large number of

channels to other devices. Cable type and quality can dramatically affect

how well the signal integrity is maintained. NI recommends using short

twisted-pair ribbon cables.

Refer to the device or cable manufacturer for additional information on

proper connectivity to the NI CB-2162 signal and ground connections.

Figure 5 shows how to connect a ribbon cable to the accessory.
