own custom levels (NI 655X).  
7. Choose a fill pattern. The following figure shows the pattern control and  
the first few signals in the window.  
Tip When generating a Marching Ones or Marching Zeroes  
waveform, it is convenient to make the waveform size a multiple of  
the number of selected channels.  
8. Click Play to generate the pattern shown in the graph on the selected  
channels. The default generation option is Continuous, but you can  
toggle this setting using the control below the graph.  
The Play and Stop buttons are shown in the following figure.  
Because the data channels on the NI digital waveform generator/analyzer  
are bidirectional, while the data is being continuously generated on all of  
the channels, as in the previous step, you can acquire the data being  
generated.  
Note Refer to the specifications for your device for information on  
the setup and hold times and propagation delays associated with  
generation and acquisition operations. At some frequencies,  
generating and acquiring data on the same channels when no cable  
is attached to the DIGITAL DATA & CONTROL (DDC) connector  
violates these timing parameters and results in incorrectly sampled  
data. For information on proper signal acquisition, refer to the  
NI Digital Waveform Generator/Analyzer Help  
.
To acquire the pattern, complete the following steps:  
1. Click the Acquisition tab.  
2. Click Play. The device acquires the digital data that you generated in the

7. Connecting Signals  
This section discusses what connections you can make to the device, and how  
to connect signals to the device for performing dynamic acquisition and  
dynamic generation. For device front panel diagrams and connector  
descriptions, refer to Appendix A: Device Front Panels.  
Connecting Cables and Accessories  
To make connections to the NI digital waveform generator/analyzer front  
panel SMB jack connectors, use a shielded 50 coaxial cable with an SMB  
plug end.  
Use an NI SHC68-C68-D2 cable for connections to the NI 654X/655X DDC  
connector. The NI SHC68-C68-D2 is designed for single-ended, high-speed  
digital signal transmission. The cable is shielded, with individual  
microcoaxial 50 lines for each signal. Use an SHB12X-B12X cable for  
connections to the NI 656X DDC connector. This cable is designed for  
differential, high-speed digital signal transmission.  
Using Accessories (NI 654X/655X Only)  
NI recommends using the NI CB-2162 single-ended digital I/O accessory to  
access the signals on the 68-pin DDC connector and to terminate the  
DIO channels. The NI CB-2162 also provides a platform for circuit  
prototyping and DUT testing. The NI CB-2162 is specifically designed for  
use with single-ended NI digital waveform generator/analyzers  
(NI 654X/655X). For more information about using the NI CB-2162, refer to  
the NI CB-2162 User Guide.  
NI also offers the NI SMB-2163 breakout box for National Instruments  
single-ended digital waveform generator/analyzers. The NI SMB-2163 offers  
coaxial SMB connectors for each channel on the DDC connector, providing  
an easy way to connect to other devices for testing and debugging. For more

Note If you are creating your own accessory to use with your  
device, you can purchase the mating connector for the VHDCI  
cable from NI (part number 778914-01).  
Whether you use NI cables and accessories or design your own, you should  
properly terminate cables to avoid improper measurements due to signal  
reflections, overshoot, and undershoot. Refer to the NI Digital Waveform  
Generator/Analyzer Help for more information about signal termination.  
Wiring for Common Measurements  
Dynamic generation and dynamic acquisition are two categories of  
applications that you can create for NI digital waveform generator/analyzers.  
This section provides information on the general wiring considerations for  
each type of application. Both examples use the NI CB-2162 for signal  
termination.  
Dynamic Generation  
When performing dynamic generation, an NI digital waveform  
generator/analyzer generates data through a matched impedance system that  
consists of a 50 output impedance, a 50 cable, and a 50 accessory.  
Figure 6 shows a diagram of such a system, using the NI 655X as an example.  
Depending on the loading of the peripheral device, you may need additional  
parallel termination resistance at the destination for optimal signal quality.  
Refer to the NI Digital Waveform Generator/Analyzer Help for more  
information about signal termination.

NI 656X Front Panels and Connectors  
The NI 656X front panels contain four connectors—three SMB jacks  
(CLK IN, PFI 0, and CLK OUT) and one 73-pin 12x Infiniband connector  
(DIGITAL DATA & CONTROL, or DDC).  
Figure 10 shows the NI 6561 front panels and pinout, which are identical to  
those of the NI 6562. Signals marked with an asterisk represent the  
complementary terminal for the differential signal of the same name. The  
DDC signals are described in Table 6. The SMB connectors are the same as  
those described in Table 7, and the LEDs are the same as those described in  
Tables 8 and 9.  
Note If you are designing a custom cabling solution with connector  
(779157-01) and cable (192744-01), the NI 656X pinout is reversed  
at the end connector. For example, the signal shown on pin 1 shown  
in the previous figure would map to pin 73 at the end connector.

Appendix B: Troubleshooting  
Device Front Panel ACCESS LED on PXI Module is Off  
When PXI Chassis is On  
If the ACCESS LED is not lit after you power on the PXI chassis, a problem  
may exist with the PXI power rails, a hardware device, or the LED.  
Note The LEDs may not light until the device has been configured  
in MAX. Before troubleshooting this issue, verify that the device  
appears in MAX.  
Troubleshoot this issue by completing the following steps:  
1. Power off your PXI chassis.  
2. Disconnect any signals from the PXI module front panel.  
3. Remove the PXI module and inspect for signs of damage. Do not reinstall  
a damaged device.  
4. Reinstall the PXI module using the procedure described in  
step 5. Installing the Hardware.  
5. Power on your PXI chassis.  
6. Verify the device appears in MAX.  
7. Reset the device in MAX and perform a self-test. Refer to  
step 6. Configuring and Testing in MAX for information on performing  
device resets and self-tests in MAX.  
8. If the ACCESS LED still fails to light, contact NI support at  
ni.com/support.  
NI Digital Waveform Generator/Analyzer Guide  
26  
ni.com  
 
   
Device Does Not Appear in MAX  
Complete the following steps if the NI device does not appear in MAX:  
1. In the MAX Configuration pane, click Devices and Interfaces to expand  
the category.  
2. Click NI-DAQmx Devices and press <F5> to refresh the list of installed  
devices.  
3. If the device is still not listed, power down the system, ensure the device  
is correctly installed, and restart.  
4. If the device still does not appear under NI-DAQmx Devices, contact  
NI support at ni.com/support.  
Device Failed the Self-Test  
The MAX self-test performs a brief test of device resources. If the device  
does not pass the self-test, complete the following steps:  
1. Reboot your system.  
2. Launch MAX and perform the self-test again. If the device still fails the  
self-test, proceed to step 3.  
3. Uninstall and reinstall NI-HSDIO.  
4. If the device still fails the self-test, contact NI support at ni.com/  
support.  
I Received a Thermal Shutdown Error  
I received the kErrorDeviceShutDownDueToHighTemperror, and my  
device shut down. What should I do next?  
To re-enable your device after a thermal shutdown, you must perform a hard  
reset, in which the device integrated circuits (ICs) are reloaded. To re-enable  
your device after thermal shutdown, complete the following steps:  
1. Power down the computer or chassis that contains the device.  
2. Review the procedure in step 5. Installing the Hardware and make any  
necessary adjustments to ensure that your device is effectively cooled.  
3. Call niHSDIO_ResetDevice(NI-HSDIO Reset Device VI) or perform  
a device reset in MAX. For more information on performing a device  
reset in MAX, refer to step 6. Configuring and Testing in MAX.

Performance Issues Using MXI Connection  
When using a MXI connection to control the PXI chassis, the MXI  
Optimization Application must be run prior to using the NI device.  
By default, this application runs automatically when Windows starts. Use of  
a MXI connection without running this application may result in a time  
exceededor internal software error, or an initialization, timeout, or  
performance issue when using the NI device.  
If you are experiencing errors and are uncertain whether the MXI  
Optimization Application ran, navigate to Start»Programs»National  
Instruments MXI and select MXI Optimization to run the application.  
If the application is not installed, refer to the software CD included with the  
MXI kit to install the software. After installation, you may be required to  
reboot the computer before using the MXI Optimization Application.  
If you continue to have initialization or performance issues, refer to the  
MXI documentation at Start»Programs»National Instruments MXI, or  
visit NI Technical Support at ni.com/support.
