Shaft Voltage Tester

The AEGIS® CAT II/III Shaft Voltage Tester™ digital oscilloscope from Electro Static Technology (Mechanic Falls, ME) enables testing of industrial motors controlled by variable frequency drives (VFDs). The tester is designed and configured to take and capture voltage measurements from the spinning shafts of motors. The digital oscilloscope comes with a conductive microfiber-tipped probe, a probe holder with magnetic base, and a carrying case. The 2-channel, full-function, 100-MHz oscilloscope has a 5.7" TFT LCD color display, a multi-language user interface, and a 5-hour rechargeable/replaceable lithium-ion battery pack. The oscilloscope is capable of sampling rates of 1 GSa/s to 50 GSa/s, and has a USB port for data transfer or flash drive storage.

RF Signal Generators

Saelig Co. (Fairport, NY) announced Rigol DSG800 RF signal generators with output frequencies from 9 kHz to 3.0 GHz. They provide an RF signal source with a maximum output of +20 dBm and frequency resolution of 0.01 Hz at any frequency. Featuring SSB noise of -115 dBc/Hz, they feature a stable internal clock for creating RF test signals. The instruments provide conventional sweep functions (step, list, logarithmic, and linear) as well as analog modulation functions including amplitude modulation, frequency modulation, phase modulation, and pulse modulation. They also offer an optional pulse train generation capability for translating serial data onto an RF link without additional hardware. The pulse train can be used as the modulating signal of pulse modulation, and can also be output as an independent pulse generator.

Product of the Month: March 2016

Paul N. Gardner Co., Pompano Beach, FL, announced the SmarTest coating thickness measurement system that consists of an app and a wireless sensor for measuring coating thickness with the help of a smartphone or tablet. The system uses Sensor-integrated Digital Signal Processing (SIDSP®) sensors combined with wireless technology to measure coating thickness. The digitally generated readings on the sensor are relayed by Bluetooth to a smartphone or tablet. The SmarTest App functions as an evaluation device, replacing a conventional coating thickness gauge. The app displays current measuring value, statistical evaluation, storage of measuring values in files, 2-point calibration, measuring unit metric/imperial switchover, and export of the series of measurement in the CSV format. All the functionalities of a smartphone are available for data transfer. The sensor can function for up to 8 hours in continuous operation, and the dual Bluetooth module ensures a long operating time in modern devices. For Free Info Visit http://info.hotims.com/61059-120

Celebrate Pi Day with NASA Goddard and Discover Pi-Sat

The Innovative Technology Partnerships Office (ITPO) at NASA’s Goddard Space Flight Center (Goddard) in Greenbelt, MD, invites you to celebrate Pi Day on March 14 and discover Pi-Sat. Current technology trends indicate a shift in satellite architectures from large, single satellite missions, to small, distributed spacecraft missions. At the center of this shift is the smallSat/cubesat architecture.

Simulation Software is Key to Orion’s Heat-Shield Success

Tecplot 360 EX data visualization and analysis software Tecplot, Inc. Bellevue, WA 800-763-7005 www.tecplot.com NASA chose Tecplot 360 EX for use in the design of the heat shield for the Orion spacecraft. Orion’s heat shield, a protective blanket built with high-tech fibers and ceramics, is crucial to mission success. The outer layer of the heat shield is designed to burn away as it heats up during re-entry into the atmosphere, thus maintaining the integrity of the inner layer and helping to ensure the survivability of the spacecraft.
