National Instruments PXIe-5606 RF Signal Downconverter

The PXIe-5606 (part numbers: 784439-01, 784440-01) from National Instruments is a PXI RF Signal Downconverter designed to meet the demands of modern engineering and research applications. The downconverter is used alongside the PXIe-5624 IF Digitizer and the PXIe-5653 RF Analog Signal Generator to create part number PXIe-5668. The PXIe-5606 has the ability to convert high-frequency RF signals to a lower level, enabling seamless digitization processes. The NI PXIe-5606 boasts an impressive frequency range, offering two distinct versions to cater to your specific needs: part number 784439-01 with 26.5 GHz or part number 784440-01 with 14 GHz. This flexibility ensures that you can tackle a wide range of RF signal conversion tasks with precision.

For RF tuned frequencies below 16 kHz, the Channel Coupling attribute is set to DC Coupled, while for downconverter center frequencies over or equal to 16 kHz, it is set to AC Coupled. Removing the DC block attachment from the PXIe-5606 RF IN connector will allow the user to measure as low as 20 Hz for center frequencies below 16 kHz.

 Featuring a 2.92 mm SMA female connector, the PXIe-5606 ensures secure and reliable connections with your RF signal source and downstream instrumentation. This connector design minimizes signal loss, allowing you to maintain the integrity of your RF signals throughout the conversion process. In addition, the PXIe-5606 offers both AC and DC coupling options, giving you the flexibility to work with various signal types and perform measurements with the accuracy you need. The PXIe-5606 has a self-calibration factor. After applying the internal self-calibration factor, the amplitude accuracy specification and the PXIe-5606 gain accuracy are identical. Resolution and temperature stability of the receiver used with the PXIe-5606 downconverter should be on par with or better than those of the PXIe-5624 digitizer.

The NI PXIe-5606 is a versatile solution suitable for a wide range of applications, including radar and electronic warfare system testing, satellite communication testing, wireless communication system development, microwave component characterization, and research in high-frequency electronics. Whether you're working in a research laboratory, manufacturing facility, or educational institution, the NI PXIe-5606 delivers the precision and flexibility you need to tackle the most demanding RF signal conversion tasks.
