Products

National Instruments provides baseband modular instruments for a variety of test, measurement, and interfacing applications. The following products cover IF and I/Q acquisition and generation, FPGA-based signal processing, and high-bandwidth data streaming.

Acquisition

Intermediate Frequency

	NI PXIe-5622 The NI PXIe-5622 is a 16-bit, 150 MS/s digitizer with a 3-250 MHz analog bandwidth and onboard digital downconversion (DDC) of up to 60 MHz of bandwidth. It supports undersampling for IF signals in the second (75 MHz to 150 MHz) and third (150 MHz to 225 MHz) Nyquist zones, and is optimized for acquiring high dynamic range IF signals Product Details>>

	NI PXI-5154 The PXI-5154 is an 8-bit, 2 GS/s digitizer when operated in single-channel mode with 1 GHz of analog bandwidth. Though it has lower resolution than other IF digitizers, its wide bandwidth enables spectral monitoring applications. Product Details>>

In-Phase / Quadrature

	NI PXIe-5122 The NI PXIe-5122 is a dual-channel, 14-bit, 100 MS/s digitizer with 100 MHz of analog bandwidth. When acquiring I/Q signals, it can digitize 100 MHz of equivalent RF bandwidth and stream it to disk for hours. Product Details>>

	NI PXI-5922 The PXI-5922 is a dual-channel digitizer optimized for extremely high dynamic range, narrowband applications. It can range from 24-bit resolution at 500 kS/s to 16 bits at 15 MS/s, providing up to 114 dB SFDR. Product Details>>

Generation

Intermediate Frequency

	NI PXIe-5442 The NI PXIe-5442 is a 16-bit 100 MS/s arbitrary waveform generator with a 40 MHz bandwidth digital upconverter (DUC) for IF generation. It is capable of streaming the entire 40 MHz of bandwidth for hours from a RAID-based hard disk array. Product Details>>

In-Phase / Quadrature

	NI PXIe-5450 The NI PXIe-5450 is a dual-channel, 16-bit 400 MS/s I/Q generator. It features differential outputs for optimum signal quality and 145 MHz of analog bandwidth. For I/Q generation applications, this is equivalent to 290 MHz of RF bandwidth. Product Details>>

FPGA Processing

IF Transceiver

	NI PCI-5640R The PCI-5640R is a software-defined dual-channel IF transceiver featuring 2, 14-bit 100 MS/s acquisition channels with 20 MHz of digital downconversion (DDC) and 2, 14-bit 200 MS/s generation channels with 20 MHz of digital upconversion (DUC). In addition, you can program an onboard FPGA to implement low-latency signal processing for stimulus-response applications. Product Details>>

Digital Interface

	NI PXI-7854R The PXI-7854R is a reconfigurable I/O device which features 96 digital lines capable of running at rates up to 40 MHz. By cabling these lines to a high-speed digital I/Q interface, you can take advantage of the device's powerful Xilinx LX110 FPGA to implement custom baseband signal processing. Product Details>>

Data Streaming

	HDD-8264 The HDD-8264 is a 12-drive, 3 TB RAID enclosure which cables to a PXI Express chassis and can sustain 600 MB/s of streaming bandwidth to or from the disks. For baseband applications, this functionality enables high-bandwidth spectrum recording for post-processing, or record and playback of IF and I/Q signals. Product Details>>
