Pentek More Than Doubles Signal Bandwidth with Cobalt Model 71651 Software Radio Module

  • Dual-channel 500 MHz A/Ds capture 240 MHz of signal bandwidth
  • Digital up and down converters tune across a wide range of IF signals
  • Multiboard programmable summation circuitry simplifies real-time beamforming
  • On-board Xilinx Virtex-6 FPGA comes preconfigured for turnkey operation
Pentek, Inc., today announced its fastest ever multichannel data converter with digital down and up converters. With two channels each of 12-bit, 500 MHz A/D and 16-bit, 800 MHz D/A, the Model 71651 delivers more than twice the bandwidth of Pentek's previous data converters. As a member of the popular Cobalt" family of high-performance XMC modules, the Model 71651 has a Xilinx Virtex-6 FPGA at its core. The FPGA is preconfigured with data acquisition and playback IP to give the module turn-key functionality, with room left for user customization.

"The Model 71651 handles a tremendous breadth of communications and radar signals," commented Rodger Hosking, vice president of Pentek. "With its high speed data converters and digital up/down converters, tuning bandwidths range from 10 kHz to 240 MHz, two and a half times our previous modules." Hosking also pointed out that the 71651 FPGA is preconfigured for use out of the box. "Our embedded IP was inspired by what our customers most often require for their applications. We're simply giving them a quick start towards their final configuration."

The Model 71651 features two input and two output RF channels, transformer-coupled to allow direct connection to HF or IF radio stages. The input channels feature 12-bit, 500 MHz A/Ds that feed data into the Virtex-6 FPGA. The output channels incorporate a Texas Instruments DAC5688 digital upconverter that translates real or complex baseband signals to any IF frequency up to 380 MHz. Dual 16-bit, 800 MHz D/As create real or in-phase (I) and quadrature (Q) analog outputs.

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.
