Vector Network Analyser Offered As Four-Port Model

The high-end RandS ZVA67 vector network analyser from Rohde and Schwarz is now also available as a four-port model. The analyser features four test ports for measurements up to 67GHz. A high dynamic range (110dB at 67GHz) and output power (6dBm at 67GHz) give the RandS ZVA67 the flexibility and performance required for characterising components and modules in the microwave and millimetre-wave ranges. It allows users in research and development to determine the S parameters of multiport devices quickly and with high precision, according to the company. The analyser's four internal signal sources reduce test system complexity and the number of instruments required, such as for measuring frequency-converting DUTs, because no external signal generators are needed. The RandS ZVA67, with an architecture that includes four ports, four integrated signal sources and eight receivers, enables measurements on multiport devices such as mixers, couplers or balanced DUTs with just one instrument. With its high output power of 6dBm and wide power sweep range of more than 40dB, the RandS ZVA67 is able to characterise the small- and large-signal behaviours of active components. Linear and nonlinear measurements can be carried out using a simple test setup. This advantage becomes apparent, for example, when measuring the S parameters or intermodulation of mixers or amplifiers or when measuring the group delay and phase of upconverters or downconverters. Offering a frequency range up to 67GHz, the four-port RandS ZVA67 covers the band intended for the wireless transmission of multimedia data (wireless HDMI). Additional applications can be found in the aerospace and defence sectors, including measurements on inter-satellite communications systems and point-to-point communications systems. The analyser has a wide dynamic range of 110dB at 67GHz and is therefore suitable for material measurements or microwave imaging applications. Frequency converters from Rohde and Schwarz extend the frequency range of the four-port network analyser to beyond 325GHz. The RandS ZVA67 enables users to advance the development of materials and technologies into much higher frequency ranges.

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.
