Wavelink Probe Achieves 25GHz Of Bandwidth

Lecroy has announced the launch of the Wavelink 25GHz high-bandwidth differential solder-in probe. This probe expands the recently introduced 13-20GHz Wavelink probe line and is said to be well matched to Lecroy's Wavemaster 8Zi oscilloscope product line, which includes bandwidths up to 30GHz. Engineers that find it insufficient to use SMA cables to input signals directly into their oscilloscope can use a Lecroy Wavelink D2505 differential probe and a Wavemaster 825Zi oscilloscope to achieve 25GHz of scope and probe bandwidth.

This latest Wavelink high-bandwidth differential solder-in probe offers rise-time performance of 17.5ps for a 25GHz probe used with a 25GHz oscilloscope, the same as the oscilloscope-only rise time. In addition, baseline electrical noise in the probe product line has been lowered to 3.1mVrms at 25GHz, and 1.6mVrms at 13GHz. The probes are also said to exhibit superior AC loading in the mid-band and high-frequency range with 350 ohms at 7GHz, 575 ohms at 13GHz, 325 ohms at 16GHz, 160 ohms at 20GHz and 120 ohms at 25GHz.

This combination can be used for accurately characterising next-generation serial data signals. The 25GHz high-bandwidth Wavelink probes are of a transmission line design with an attenuating tip followed by an amplifier output to a differential transmission line connecting to the oscilloscope with a platform/cable assembly. The minimum AC loading (Zmin) of the new Wavelink probe at high frequency is 13GHz to 20GHz.

Lecroy has also improved on the design of its damping resistors on the solder-in tip field replaceable so that an engineer, faced with a damaged tip, can simply solder a new damping resistor to the tip and quickly resume work. Each solder-in probe comes standard with 10 spare damping resistors, while more can be ordered as required.

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.
