New digital storage oscilloscopes

The new Tektronix TBS2000B series of digital storage os- cilloscopes is now available locally from Comtest. The series has been developed to meet the performance, usability and affordability needs of engineers and edu- cators, with easy-to-use controls, automated measure- ments and built-in instruction features. The TBS2000B scopes extend the performance of the TBS2000 portfolio to 200 MHz with 2 GS/s maximum sample rate. This series follows the release of Tektronix’s series 3 and 4 oscilloscopes, as the organisation remains committed to investing in a broad portfolio of benchtop solutions. The TBS2000B Series is designed for easy operation and fast hands-on learning with a range of key features. - Large 9-inch WVGA display and 15 horizontal divi- sions – the most in its class – provide 50% more sig- nal visibility. - 5M point record length, 200 MHz bandwidth, and 2 GS/s sample rate capture and display significantly more signal to debug and validate designs faster. - New lower-noise front-end design offers better signal integrity and more accurate measurements. - TekVPI™ probe interface supports a wide range of active, differential and current probes with automatic scaling and units. - On-waveform cursor readouts with search and mark features enable easy identification of events that oc- cur in the acquired waveform. - Bandwidth is field-upgradeable from 70 MHz to 100 MHz to 200 MHz. - Includes Wi-Fi support (via USB Wi-Fi dongle), 2 USB host ports, and 100-BaseT Ethernet for easy collaboration. Providing 100% compatibility with existing designs, the Michell Instruments, locally represented by Instrotech, offers the Condumax II On-Line, a fully self-contained hydrocarbon dew point analyser which uses the proven Dark Spot™ hydrocarbon dew point measurement principle. Combining a hydrocarbon dew point cell and water dew point measurement in the same compact and lightweight EExd enclosure, Condumax II On-Line requires only mains power to operate. Condumax II On-Line uses a patented chilled mirror optical measurement technique that is radically different to that of any other instrument. Sensitivity of better than 1 ppm molar (1mg/m3) of condensed hydrocarbons enables the analyser to detect the almost invisible films of condensate characteristic of hydrocarbon gases at dew point, due to their low surface tension and colourless appearance. The result is a breakthrough in accuracy and repeatability. The optical sensor comprises an acid etched, semi- On-line hydrocarbon dew-point analyser

TBS2000B series is a drop-in replacement for TBS2000 series oscilloscopes, with the same form factor and pro- grammable interface. Hands-on learning The TBS2000B is ideal for university and training environ- ments, with built-in features that make instruction in engi- neering fundamentals easier for students and teachers. - HelpEverywhere offers instant tips within key menus, including measurement information, application tips and guidance in the form of text and graphics. - TekSmart Lab™ network software helps instructors set up and monitor many instruments from one PC. - Courseware ecosystem lets instructors load informa- tion into the TBS2000B to help students during lab sessions. - Autoset, cursors and automated measurements can be disabled to facilitate teaching basic concepts. The new Tektronix TBS2000B series of digital storage oscilloscopes has been developed to meet the needs of engineers and educators. matt stainless steel ‘mirror’ surface with a central conical-shaped depression, which is chilled during a measurement cycle. Collimated visible red light is focused onto the central region of the optical surface. In the dry condition, the incident light beam is dispersed by the matt surface providing a base signal to the optical detector. During a measurement cycle, hydrocarbon condensate is formed on the optical surface and it becomes reflective due to the low surface tension of the con- densate. An annular ring of light forms around the detector and there is a dra- matic reduction in the scattered light intensity within the central Dark Spot™ region. For more information contact Comtest.
