Wavesurfer Oscilloscopes in 200MHz-1GHz Bandwidth

Lecroy has launched a line of Wavesurfer MXs-B and MSO MXs-B oscilloscopes ranging from 200MHz to 1GHz bandwidth. The new oscilloscopes deliver a sample rate of up to 10GS/s and memory of 25Mpts, as well as feature set enhancements that include a Sequence Mode data-acquisition capability. They feature debug tools such as Wavestream Fast Viewing Mode, Wavescan Search and Find, a variety of serial data trigger and decode packages, plus the Labnotebook documentation and report generator.

The MSO MXs-B models provide 18 digital channels that can sample at 1GS/s for debugging analogue and digital mixed-signal systems. Wavesurfer uses a bright 10.4in colour display to allow room for time-correlated views of mixed-signal systems and non-time-domain analysis. Sequence mode is a versatile acquisition mode that segments the oscilloscope memory and combines up to 10,000 acquisitions in to a single, sequential waveform. This technique enables capturing of very fast pulses in rapid succession with trigger rates of up to 1.25 million waveforms per second.

Additionally, Sequence Mode can be used to optimise memory usage by only capturing data when data is present, ignoring large spans of dead time between pulses or bursts. In the end, all the waveforms are displayed and time stamped for further analysis. Sequence mode in combination with the 25Mpts of memory in Wavesurfer MXs-B enables extremely fast triggering over very long periods of time, maintaining a high sample rate throughout and ensuring that the user always captures the fastest edges or the rarest glitches.

Wavescan provides the ability to locate unusual events in a single capture or scan for an event in any acquisitions over a long period of time. Users select from more than 20 search modes (frequency, rise time, runt, duty cycle), apply a search condition and begin scanning. Since the scanning 'modes' are not simply copies of the hardware triggers, the utility and capability is much higher. For instance, there is no 'frequency' trigger in any oscilloscope, yet Wavescan allows 'frequency' to be quickly 'scanned' for.

This allows the user to accumulate a data set of unusual events that are separated by hours or days, enabling faster debugging. Now users can efficiently create complete and detailed waveform reports directly in the oscilloscope. An all-in-one solution for annotating and sharing information, Labnotebook simplifies results recording and report generation by eliminating the multi-step processes that often involve several pieces of equipment.

Labnotebook enables users to focus on results rather than the process, as it saves all displayed waveforms and the relevant DSO setups with the saved waveform. The user can add freehand notes with a stylus or as text and convert the complete report to pdf, rtf, or html. Reports can then be printed or emailed directly from the scope. The Wavesurfer MXs-B and MSO MXs-B oscilloscopes never bog down with long memory, even when displaying FFTs, measurements and serial data decodes.

Their architecture allows the user to maintain control over their measurements and never forces them to wait for complex calculations or measurements to complete. The serial data trigger and decode options for Wavesurfer provide time-saving tools for serial bus debug and validation. The serial data trigger will quickly isolate events on a bus, eliminating the need to set manual triggers. Protocol decoding is shown directly on the waveform with an intuitive, colour-coded overlay and presented in binary, hex or ASCII.

Decoding on the Wavesurfer is fast, even with long memory, and zooming in to the waveform shows precise byte-by-byte decoding. To further simplify the debug process, all decoded data can be displayed in a table below the waveform grid. Selecting an entry in the table with the touch screen will display just that event. Additionally, built-in search functionally will find specific decoded values. MSO MXs-B and the Wavesurfer MXs-B offers tools for trigger and decode of a set of popular serial data signals, such as I2C, SPI, UART, CAN, LIN, Flexray, USB, ARINC 429, MIL-STD-1553, MIPI D-PHY, DigRF3G and Digital Audio.

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.
