RF Signal Generator Offers Low Phase Noise

Aim-TTi has launched the TGR6000, a 6GHz RF signal generator that the company claims is priced at less than half that of the lowest-cost 6GHz generators available previously. The TGR6000 covers a frequency range from 10MHz to 6,000MHz at an output level of between -110dBm and +7dBm, adjustable in 0.1dB steps. The frequency resolution is 10Hz and the internal timebase stability is better than 1ppm. The generator offers low phase noise, residual FM and spurious signal responses.

An external reference can be used where higher accuracy is required. User level compensation tables can be loaded in order to calibrate an entire test setup. The TGR6000 is intended for CW signal applications and has no built-in modulation capability. However, a sweep generation system is included that covers the full frequency range and incorporates a sophisticated step or list sweep covering both frequency and amplitude. In step sweep, the frequency and/or amplitude are stepped between two fixed points using up to 1,000 steps, which can have a fixed time period or a triggered interval.

Sweeps can be linear or logarithmic, up or down. In list sweep, frequency and amplitude points are defined within a table, enabling any sweep pattern to be used. Full digital remote-control facilities are available through the RS232, USB and LAN (Ethernet) interfaces and an additional GPIB interface is optionally available. The TGR6000 is housed in a half-rack 2U high case with backlit LCD display and keyboard in addition to a spin-wheel control. It costs GBP2,850 (plus VAT) in the UK.

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.
