NEXT GENERATION BASIC OSCILLOSCOPE LAUNCHED
IMPROVING GAS NETWORK SURVEYS
At a press conference at Tektronix’s Bracknell facility, Peter Bachmayr, technical marketing manager, introduced the TBS2000, a ‘next generation’ basic oscilloscope. This new instrument is said to provide a level of design insight previously not available in this class of instrument, and is capable of capturing and displaying more signals than before. The oscilloscope offers a 20Mpoint record length with
single-knob pan and zoom, providing the ability to capture long time duration signals and easily navigate to find important details. It also features a 9in WVGA display so can display 15 horizontal (time) divisions, allowing users to see 50% more signal than other scopes, the company claims. Models are available with 70 MHz or 100 MHz bandwidth and
with two or four channels; and it enables users to easily analyse signals with on-waveform cursor readouts and 32 automatic measurements. Of additional benefit, this is the only basic oscilloscope with the TekVPI Probe interface for better application coverage with a wide range of active and current probes. Additional beneficial features include built-in help and an integrated handbook to enable users to quickly come up to speed. The instrument is suitable for use by designers and in
education. Design engineers use general-purpose oscilloscopes to prototype, debug and validate designs of new products and for general troubleshooting. In education, such oscilloscopes give students hands-on experience in electronics engineering when educators need to efficiently mentor and monitor large groups of students. The TBS2000 meets these requirements and more, the company explains. In fact in education, the instrument includes a built-in courseware lab viewer, enabling students to learn through hands-on labs.

Exterior aircraft noise certification tests are required by aviation regulators, with the tests establishing certified aircraft Effective Perceived Noise Levels (EPNLs) for approach, flyover and sideline. To help, Dassault Aviation is using an acoustic data acquisition and analysis system from Brüel & Kjær to perform noise certification tests on its new Falcon 8X business jet. The system uses three GPS-synchronised data
acquisition stations which are distributed around the test area. These communicate via WiFi and are controlled from a central monitoring station. Each remote location measures and records noise and has a webcam, with one station monitoring weather data. The central monitoring station controls the data acquisition, uploads data,

interfaces to flight-track data and layered weather data, and calculates results. The system is based on the modular Brüel &
Kjær PULSE LAN-XI data acquisition hardware, which provides the measurement data for the official calculation of EPNL levels. This data is corrected, 1/3rd octave noise measurements compliant with the requirements for aircraft noise certification measurements in accordance with ICAO Annex 16, Volume I, amendment 9. Not only can this compute EPNL values
including background noise, flight track and weather corrections, but it can calculate intermediate results such as OAL, PNL, PNL Tmax, PNLT curve and 10 dB down points, which are used during aircraft
development testing to ensure designs are on target to meet requirements.

INFICON has introduced the lightweight IRwin methane leak detector and probe system. With its highly sensitive IR sensor, this reacts quickly to the presence of natural gas and recovers quickly after exposure, minimising the risk of an operator missing a leak during a survey. Capable of measuring concentrations as low as 1ppm, this has a built-in GPS receiver that logs the surveyed route and pinpoints the location of detected leaks, while the highly selective IR-sensor reduces cross-sensitivity to other gases. An ethane analysis function enables the operator to distinguish between marsh gas and natural gas within minutes. The unit can be carried easily in its shoulder case or harness. It is connected to a mono-wheel carpet probe which is designed to cover large paved surfaces but can, with its single wheel, also reach into corners, cracks and places with limited access. A flip of the wrist turns the probe 180˚ and enables the operator to reach under parked vehicles and other obstacles. The carpet probe can also be locked in position while lifting the unit over obstructions.

PERMEABILITY MEASUREMENT
Vapours – usually water or hydrocarbon – can result in machines that jam, electronics that fail, foods that rot, metals that rust, and drugs that lose potency. Testing the vapour permeability of both the materials and any suspect component or enclosure can, however, help to prevent this. Versaperm’s latest permeability
measuring instrumentation offers a quick and easy way to determine the vapour permeability for virtually any system, component, product or material. With this, the user can accurately quantify the problem and
check for practical solutions. It is suited to both development and QC roles. The system is usually accurate in
the parts per million (ppm) range, however with some vapours and materials can be accurate in the parts per billion (ppb) range. In some cases testing takes just 30 minutes. According to the company, its latest
instrument and specialised sensor range can measure permeability not just for water vapour, but for virtually any gas or vapour used by industry including oxygen, carbon dioxide, hydrocarbons, helium and nitrogen. The system can measure several material samples, seals, enclosures or products at a time.
