40-265-304 - Pickering Interfaces Ltd.
The 40-265 range consists of 6, 4 or 2 channel modules (this version is the 4-channel, 2k) that simulate the operation of a range of strain gauges making it ideal for testing strain gauge meters and a wide variety of industrial control systems. The range provides a simple way of replacing in house developed sensors with a low cost simulator having excellent performance. The 40-265 uses the same resistor bridge techniques that real life strain gauges are based on, ensuring accurate emulation under all conditions. Each simulator channel includes an independent input for the Excitation Voltage and a bridge output. The Excitation Voltage port can be driven by an AC or a DC source. The bridge circuit includes three fixed resistors and a fourth programmable resistor that can be adjusted over a narrow resistance range with fine adjustment capability and excellent accuracy. The adjustment range provided is sufficient to simulate quarter, half or full bridge circuits. The standard bridge impedances are 350, 1k, 1.5k, 2k and 3k. These modules are extremely simple to use, the variable resistor element can be programmed using a simple resistance call. The module supplies the user with the resistance value required to balance the bridge, and the resistance call to the simulator can be varied above and below this value to simulate extension and compression of the strain gauge resistor.

Infinite Industrial Informatics Lt
Sigfox is a communication protocol that is used to read data from sensors through a fixed network of base stations. It works like a low cost “SMS” service. As an end-user, you only need to buy a subscription to connect to the data network operated by SIGFOX. Sigfox employs a proprietary Ultra Narrow Band (UNB) radio technology that enables communication using the Industrial, Scientific and Medical ISM radio band, which uses 868MHz in Europe and 902MHz in the US. It has the advantage of covering larger areas than other fixed local systems.The overall Sigfox network topology has been designed to provide a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure. The density of the cells in the Sigfox network is based on an average range of about 30-50km in rural areas and in urban areas, where there are usually more obstructions and noise is greater, the range may be reduced to between 3 and 10km.According to the latest numbers, Sigfox has a nationwide live coverage in 6 countries and in 14 other countries it is deploying and rolling out ts network. By end 2018, the ambition is to cover 60 markets.

Semilab
There is no disputing the detrimental effect of metallic contamination on the integrity of the critical gate oxide used in integrated circuits. During high temperature processing contamination in the silicon wafer often precipitates as a defect at the Si/Dielectric interface or segregates to the dielectric in either case it has the potential to cause pre-mature device failure and a reduction in product yield. The probability of metallic contamination impacting yield is a function of the chip size (e.g. technology node/critical dimension) and the defect density (e.g. the amount of contamination), such that as device dimensions decrease, maintaining yield requires a corresponding reduction in contamination. Figure 1 clearly demonstrates the reality of this relationship over the past 25 years, during which time the IC industry has experienced a more than 3 orders of magnitude reduction in typical background Fe concentration observed in new fabs. More importantly is the near-term projection, where over the next few years another order of magnitude reduction is needed to meet the requirements of state of the art Si IC manufacturing; with white pixel reduction in CMOS Image Sensors being a major stimulus for this effort.

Pasternack Enterprises, Inc.
Voltage variable attenuator series offers up to 60 dB of attenuation across broad frequencies. The frequency range of the voltage variable attenuator components is from 400 MHz to 18 GHz. This line of voltage variable attenuators is most commonly deployed in applications such as electronic warfare, instrumentation, point-to-point and point-to-multipoint radios, fiber optic and broadband telecom, microwave radio and VSAT, military radios, radar, ECM, SATCOM and sensors, and R&D.In most communications systems, the RF components used (transmitters, receivers, mixers, multipliers, attenuators, amplifiers, VCO’s, phase locked loops, etc.) may require specific power levels to run optimally. These power levels may differ from one component to the next in a system network. These may require the attenuation level to be finely adjusted to account for changes in received signal levels or to optimally match the input power into a sensitive circuit.Pasternack’s PIN diode-based voltage variable attenuators (VVAs) provide accurate control and broadband flatness where the output level can be adjusted continuously by varying an analog voltage on the input control line. These VVA’s are ideally suited for use with variable gain amplifiers, power level control, feed-forward amplifiers, and automatic level control (ALC) circuits.Like the other over 40,000 RF, microwave and millimeter wave components from Pasternack, this voltage variable attenuator VVA series is in-stock. Not only are these VVA components in stock, they will ship the same day as ordered.

Model T753U - Teledyne Advanced Pollution Instrumentation
The Model T753U is a portable, microprocessor based precision Calibrator for Ozone gas instruments and sensors. Using a sophisticated Ozone generation system, combined with a sensitive photometer and pneumatic design, the T753U produces stable and reliable concentrations of Ozone in a convenient and rugged package based on our popular T750/U Portable Multigas Calibrator platform. The T753U is housed in a high-density, molded travel case which includes an integral handle and wheels for durability and ease of use in the field for virtually any application. An internal zero air option extends the T753U's capabilities to also provide a clean and dry source of zero air, eliminating the need for a separate source of zero air. The internal zero air source module contains a software driven electronic inlet valve manifold allowing the calibrator to automatically switch between internal and external zero air sources depending on the application needs.The T753U operates in two modes; a high range, and a low range, or "fractional" mode, for producing accurate Ozone levels down to 2 ppb which meets the latest US EPA calibration requirements for Trace-level Ozone gas instruments. The mode is automatically selected based on the Ozone concentration range chosen by the user. To ensure high accuracy and stability of the Ozone output, the calibrator constantly measures the Ozone concentration being produced with an internal photometer and uses it to actively control the Ozone generator in real-time. The internal photometer can be certified by another external Reference Standard by simply using the 'photometer input loop' located beneath the fold up panel. The T753U Portable Ozone Calibrator combines performance and convenience for the most demanding applications.
