reference clock signal and drive this reference to the backplane. To use an external frequency

reference, you must connect this signal to the FREQ REF IN connector on the NI 5600 module front

panel.

3. (Optional) Using the semi-flexible coaxial cable, connect the bidirectional PXI 10 MHz I/O

connector on the NI 5600 front panel to the upper 10 MHz OUT connector on the NI 5600 front

panel.

Caution Incorrect torque at SMA connections can degrade signal fidelity, phase-locked loop (PLL)

performance, and insertion loss. Use an SMA torque wrench to ensure all SMA connections are

properly torqued to 1 N · m.

4. Carefully tighten all SMA connectors to 1 N · m using an SMA torque wrench (not included), as

shown in Figure 3. Tighten only until the wrench clicks.

5. Plug in and power on your PXI chassis and controller system.

6. Verify that the POWER LED on the NI 5600 RF downconverter module is illuminated. If the LED

is not illuminated, refer to Appendix B: Troubleshooting.

You have completed installation of your NI 5660 RF vector signal analyzer.

Cooling Considerations

When installing a PXI module, follow the guidelines in the Maintain Forced-Air Cooling Note to Users

document included in the kit to ensure that the device is cooled effectively.

Caution Inadequate air circulation could cause the temperature inside the chassis to rise above the

optimal operating temperature for the RF vector signal analyzer hardware modules, potentially

causing thermal shutdown, shorter life spans, or improper performance.

7. Configuring and Programming the NI 5660

Use Measurement & Automation Explorer (MAX) to configure your National Instruments hardware.

MAX informs other programs about which devices reside in the system and how they are configured.

MAX is automatically installed with the driver software.

To use MAX to configure, self-test, and functionally test the NI 5660 RF vector signal analyzer

hardware modules, complete the following steps:

1. Launch MAX by navigating to Start»All Programs»National Instruments»Measurement &

Automation or by clicking the MAX desktop icon.

2. In the Configuration pane, double-click Devices and Interfaces to see the list of installed devices.

3. Expand the Traditional NI-DAQ (Legacy) Devices folder. You will see a list of installed devices

that includes the NI 5600 and NI 5620 modules (your default device names may vary).

Note If you do not see the NI 5600 and NI 5620 modules listed, refer to Appendix B:

Troubleshooting.

4. Note the device numbers assigned to your RF vector signal analyzer hardware modules by MAX.

These numbers are used when programming the RF vector signal analyzer.

Complete steps 5 through 11 to self-test both modules.

5. Right-click NI PXI-5600 and select Properties.

6. The Configuring Device dialog box appears. Click Test Resources to self-test the NI 5600 RF

downconverter hardware module. The MAX self-test performs a basic verification of hardware

resources.

7. The NI-DAQ Configuration Utility dialog box appears to confirm your self-test. Click OK to return

to the Configuring Device dialog box.

Note If the NI 5600 RF downconverter module fails the self-test, refer to Appendix B:

Troubleshooting.

8. In the NI 5600 Configuring Devices dialog box, click OK to return to MAX.

9. Right-click NI PXI-5620 and select Properties.

10. The Configuring Device dialog box appears. Click Test Resources to self-test the NI 5620 IF

digitizer hardware module.

11. The NI-DAQ Configuration Utility dialog box appears. Click OK to return to the Configuring

Device dialog box and continue with the NI 5620 test panel.

Note If the NI 5620 IF digitizer module fails the self-test, refer to Appendix B: Troubleshooting.

You have completed setup, configuration, and testing of the NI 5660 RF vector signal analyzer.

Rename Both Modules

MAX allows you to rename both NI 5660 hardware modules. The MAX name is used in software to

operate the NI 5660 hardware resources. You are not required to change the module names from the

default names assigned by MAX, but doing so can make your program more readable. If you do not wish

to rename the modules, proceed to the Acquiring Data Interactively section.

To rename both NI 5660 hardware modules, complete steps 1 through 7.

1. Right-click NI PXI-5600 and select Rename from the shortcut menu.

2. Enter the new name for the NI 5600 module.

Note The device name must consist only of alphanumeric and underscore characters.

3. Click OK.

4. Right-click NI PXI-5620 and select Rename from the shortcut menu.

5. Enter the new name for the NI 5620 module.

6. Click OK.

7. Verify that the new names for both modules are displayed before proceeding to the next section.

Acquiring Data Interactively

To interactively acquire data and perform measurements with the RF vector signal analyzer, use the

included RFSA Demo Panel. The RFSA Demo Panel is accessible from within MAX at Tools»

Soft Front Panels»NI5660 - RFSA Demo Panel and from the Start menu at Start»All Programs»

National Instruments»NI-RFSA»5660 Demo Panel.

Tip If an external signal source is not available, the signal from the 10 MHz OUT connector on the

NI 5600 RF downconverter module front panel can be used as a source to verify proper RF vector

signal analyzer installation and as a live signal for the RFSA Demo Panel. To use this signal, connect

the 10 MHz OUT connector of the NI 5600 module to the INPUT connector on the NI 5600 RF

downconverter module front panel.

The RFSA Demo Panel (shown in Figure 4) provides a convenient software interface with which

you can operate the RF vector signal analyzer hardware to perform common frequency-domain and

I/Q measurements.

Tip Press <Ctrl-H> to view context-sensitive help for all RFSA Demo Panel controls and indicators.
