NI Introduces Measurement Suite For Mobile Wimax

National Instruments (NI) has introduced the NI Measurement Suite for Mobile Wimax, a software suite that can be used with modular RF instrumentation for automated testing of Mobile Wimax devices. Using the software, engineers can perform Mobile Wimax (IEEE 802.16e-2005) component and device testing faster and with accuracy and flexibility. Based on PXI Express instrumentation powered by multicore technology, the suite is claimed to be able to perform error vector magnitude (EVM), power and spectral measurements three to five times faster than traditional instruments.

National Instruments said PXI Wimax systems also provide a low-cost research-and-development grade instrumentation alternative to traditional instruments. With a typical residual EVM accuracy of -46dB at 3.5GHz (-10dBm), the company claimed the test system can perform more accurate measurements than alternative production test-grade instruments. Additionally, the suite provides engineers enhanced flexibility with the same equipment used for testing Mobile Wimax devices to test hardware that complies with other standards such as Fixed Wimax, wireless local area network (WLAN), GPS, and GSM/Edge/WCDMA cellular standards.

The Measurement Suite for Mobile Wimax supports channel bandwidths from 1.25 to 28 MHz and fast Fourier transform (FFT) sizes 128, 256, 1,024 and 2,048, as well as all Mobile Wimax modulation types with both convolution coding and turbo convolution coding. The Measurement Suite for Mobile Wimax can also generate or analyse signals with up to eight zones and 16 bursts. Combined with the NI PXIe-5663E RF vector signal analyser and NI PXIe-5673 RF vector signal generator, the measurement suite also provides continuous frequency coverage from 85MHz to 6.6GHz.

By including the NI Signal Analysis Toolkit for Mobile Wimax and the NI Signal Generation Toolkit for Mobile Wimax, the suite offers programming APIs and virtual instrument panels for signal generation and analysis in programming environments including the NI Labview graphical system design platform. In addition to a Labview API, the toolkits install with an equivalent C-style API for engineers using C, C++, .Net, or similar programming language. The Measurement Suite for Mobile Wimax supports multiple PXI hardware configurations to meet different application needs.

A standard NI test bundle for Mobile Wimax includes an NI PXIe-5663 6.6 GHz vector signal analyser, NI PXIe-5673 6.6GHz vector signal generator, NI PXIe-1075 18-slot high-bandwidth chassis and a NI PXIe-8108 dual-core controller to provide high-performance flexibility to a variety of automated test systems.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
