NI Communications Instruments Speed Signal Generation by More Than 300 Times.AUSTIN, Texas -- New National Instruments Hardware and Software Provide Dramatic Advances from Baseband to RF Engineers and scientists now can generate RF and baseband signals more than 300 times faster with the new National Instruments (Nasdaq:NATI NATI National Association of Teen Institutes NATI Newfoundland Association of Technical Industries ) PXI-5671 RF vector signal generator and the new NI PXI-5441 arbitrary waveform generator An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). with onboard signal processing. With the release of these modules and the new NI Modulation Toolkit 3.0 for LabVIEW, National Instruments offers a complete modular solution for generating high-speed communications signals. The PXI-5671 module is a three-slot RF vector signal generator that delivers signal generation from 250 kHz to 2.7 GHz, 20 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. of real-time bandwidth and up to 512 MB of memory. With the onboard digital upconverter on the module, engineers can achieve more than 300 times faster waveform download time or playback duration. This functionality is ideal for engineers who require data streaming with rapid response time for software-defined radio (SDR See software defined radio. ) or faster download times for satellite radio applications. Engineers also can take advantage of the module's configurable signal processing parameters such as prefilter gain and offset, finite impulse response (electronics, DSP) Finite Impulse Response - (FIR) A type of digital signal filter, in which every sample of output is the weighted sum of past and current samples of input, using only some finite number of past samples. (FIR) filters, cascaded integrator-comb (CIC CIC circulating immune complexes. CIC Circulating immune complexes. See Immune complexes. ) filters, a numerically controlled oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air (NCO NCO abbr. noncommissioned officer NCO noncommissioned officer NCO n abbr (Mil) (= noncommissioned officer) → Uffz. ) and IQ mixing. The new PXI-5441 module, a 100 MS/s arbitrary waveform generator for producing standard functions, arbitrary waveforms and waveform sequences, introduces onboard signal processing functionality. Onboard signal processing adds baseband interpolation/pulse shaping and quadrature quadrature, in astronomy, arrangement of two celestial bodies at right angles to each other as viewed from a reference point. If the reference point is the earth and the sun is one of the bodies, a planet is in quadrature when its elongation is 90°. digital upconversion capability for generating baseband I/Q I/Q Inphase and Quadrature and intermediate frequency (IF) signals up to 43 MHz. The PXI-5441 is the industry's first arbitrary waveform generator to combine these operating modes in a single module with instrument-quality analog specifications. The PXI-5671 and PXI-5441 modules ship with the new NI Modulation Toolkit 3.0 for LabVIEW. In addition to its ability to rapidly prototype any standard-specific or custom digital communication system, the software now includes channel coding, channel equalization and channel models as well as new, easy-to-use pallet functions for ASK, PAM, AM-VSB and AM-SSB modulation formats. Because the Modulation Toolkit tightly integrates with NI hardware, engineers can use the software to easily perform hardware-in-the-loop testing. "Customers benefit from the increase in signal generation speed due to the quadrature digital upconversion capability onboard the NI PXI-5671 and PXI-5441 modules," said Joseph E. Kovacs, NI RF product marketing manager. "Using this new technology, engineers can reduce their download and signal generation time from 180 seconds to 0.5 seconds." The National Instruments RF and communications product line extends the speed and flexibility of virtual instrumentation into the GHz frequency range. With these tools, engineers have access to customizable functionality unavailable with traditional instrumentation for applications including radio frequency identification See RFID.

The tag, also known as an "electronic label," "transponder" or "code plate," is made up of an RFID chip attached to an antenna. ), wireless sensors, wireless telemetry and wireless standards-based testing such as IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.15.4 (Zigbee). Furthermore, researchers and students can use the tools' flexibility to prototype next-generation communication systems such as multiple input, multiple output (MIMO (Multiple Input/Multiple Output) Pronounced "my-mo," it is the use of multiple transmitters and receivers (multiple antennas) on wireless devices for improved performance. ).
