hardware, performs waveform programming and generation, and performs
basic modulation tasks using LabVIEW VIs or LabWindows/CVI
functions. In the case of NI 5670/5671/5672 RF signal generators, the
NI-RFSG instrument driver operates the NI 5610 upconverter module
and the NI 5421/5441/5442 AWG module as a single instrument.
Optional add-on software available from NI, including the
Modulation Toolkit and the Spectral Measurements Toolkit, extends
the capability of NI RF signal generators to include additional
modulation-domain and frequency-domain tasks. The NI RF signal
generator hardware-software architecture is shown in Figure 7.

Appendix C: Troubleshooting
Module Front Panel ACCESS LED is Off When PXI Chassis is On
If the ACCESS LED fails to illuminate after you power on the PXI chassis,
a problem may exist with the PXI power rails, a hardware module, or
the LED.
Note The LEDs may not light until the device has been configured in MAX. Before
proceeding, verify that the NI RF signal generator module(s) appear in MAX.
Troubleshoot this issue by completing the following steps:
1.Power off the PXI chassis.
2.Disconnect any signals from the PXI module front panels.
3.Remove any module front panel connections from the NI RF signal
generator hardware module(s).
4.Remove the NI RF signal generator hardware and inspect for damage.

Performance Issues Using A MXI Connection
When using a MXI-3 connection to control the PXI chassis, you must run
the MXI Optimization Application prior to using the NI RF signal
generator. By default, this application runs automatically when Windows
starts. Using a MXI connection without running this application may result
in a
time exceeded or internal software error, or an initialization,
timeout, or performance issue when using an NI RF signal generator.
If the MXI software is not installed, refer to the setup instructions included
with the MXI kit to install the software from the MXI software CD or
National Instruments Driver CD. After installation, you may be required
to reboot the computer before using the MXI application.
If you continue to have initialization or performance issues, refer to the
MXI documentation included in your MXI kit, or visit NI Technical
Support at
