MAX lists all modules installed in the chassis. Your default names may vary.
Note
If you do not see your module listed, press <F5> to refresh the list of
installed modules. If the module is still not listed, power off the system, ensure
the module is correctly installed, and restart.
4.
Record the identifier MAX assigns to the hardware. Use this identifier when
programming the NI 5668R.
5.
Associate the hardware modules that comprise your device.
a)
Select the NI 5606 that is identified as not configured in the configuration tree.
b)
In the Associated Devices section, select the appropriate module from each system
component drop-down listbox.
For the NI 5668R, you must associate the NI 5624R IF digitizer module and the
NI 5653 LO source module with the NI 5606 RF downconverter.
c)
Click
Save
in the MAX toolbar.
Note
Module associations may be lost when you move the modules to
different chassis slots.
6.
Self-test the device modules by selecting the modules in the configuration tree, and
clicking
Self-Test
in the MAX toolbar. Repeat this step for all modules in your NI 5668R
system.
The MAX self-test performs a basic verification of hardware resources.

Self-Calibration
It is important to perform a self-calibration after first connecting your system because of
cabling and mismatch effects and some degree of residual error, which result from module
interconnections. You can determine and reduce these undesired effects through self-
calibration, which adjusts the NI 5668R with respect to an onboard high-precision calibration
tone. Additionally, you should periodically run a self-calibration to adjust for performance
drifts that occur with product aging.
The NI 5668R modules are independently calibrated at the factory; however, you should
perform a self-calibration in any of the following situations:
•
After first installing and interconnecting your NI 5668R system
•
When there is a physical change to any of the system components, such as replacement of
modules
