New Tetra Air Analyzer from Willtek

The TETRA Quality of Service is of major concern for network operators and user groups in the public safety and security sector. Willtek’s 8140 TETRA AirAnalyzer now helps to discover dead spots and handover problems. It monitors the radio communication and offers users comprehensive post-processing capabilities.

The TETRA AirAnalyzer enables you to test network performance and load to make safety-critical communication as reliable as possible. It records, displays and analyses the complex communication between one or several TETRA mobile stations and a TETRA base station.

The TETRA AirAnalyzer can also be used as a versatile protocol analyzer for the development of TETRA terminals, IOP tests, or monitoring and analysing signalling.


What is MEMS Technology?

Micro-Electro-Mechanical Systems (MEMS) is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate through microfabrication technology. While the electronics are fabricated using integrated circuit (IC) process sequences (e.g., CMOS, Bipolar, or BICMOS processes), the micromechanical components are fabricated using compatible "micromachining" processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices.

MEMS promises to revolutionize nearly every product category by bringing together silicon-based microelectronics with micromachining technology, making possible the realization of complete systems-on-a-chip. MEMS is an enabling technology allowing the development of smart products, augmenting the computational ability of microelectronics with the perception and control capabilities of microsensors and microactuators and expanding the space of possible designs and applications.

Microelectronic integrated circuits can be thought of as the "brains" of a system and MEMS augments this decision-making capability with "eyes" and "arms", to allow microsystems to sense and control the environment. Sensors gather information from the environment through measuring mechanical, thermal, biological, chemical, optical, and magnetic phenomena. The electronics then process the information derived from the sensors and through some decision making capability direct the actuators to respond by moving, positioning, regulating, pumping, and filtering, thereby controlling the environment for some desired outcome or purpose. Because MEMS devices are manufactured using batch fabrication techniques similar to those used for integrated circuits, unprecedented levels of functionality, reliability, and sophistication can be placed on a small silicon chip at a relatively low cost.


M150 Probe Station from Cascade

Cascade Microtech is bringing to market the M150 Measurement Platform that for the first time brings high-performance
and precision electrical measurement for any type of 150mm device on a single platform. The M150 is a revolutionary
configurable design that serves as an entry-level measurement system for research and development of a wide variety of high-speed devices. This is the first product of its kind that is completely modular and affordable while maintaining Cascade Microtech’s legendary precision measurement capability.
The M150 Measurement Platform maintains the system accuracy necessary for measurements of high-speed wafers at 150mm and below, as well as packages, boards and biological materials. Unlike standard wafer probers, the M150’s user-interchangeable parts include custom device under test (DUT) holders that can be easily changed and optimized for a wide variety of applications including:
• 150mm wafers for compound semiconductors
• Packaged chips and multi-chip modules
• Shards of large format silicon wafers
• Motherboards
MEMS devices
• Investigation of biostructures and applications including lab-on-a-chip

The M150 is not just revolutionary in its configurability. With this introduction Cascade Microtech has created an easier way to buy systems that were previously complex measurement tools requiring days to configure in order to purchase. The customer can buy two ways—buy a pre-configured application-specific system or configure his own system with an online system-builder or configurator. Further, Cascade Microtech provides system accessories designed to support each application. These include application-optimized probes, cables, precision positioners and other accessories. All the user has to do is determine their application need and select the appropriate measurement system and accessories. When the customer’s measurement needs evolve they can select a new accessory kit, and, if necessary, the appropriate
measurement system modules and they are up and running. Unlike the purchasing process of the past, the need to go through a separate purchasing, bidding and budget authorization cycle is eliminated.

M150 can be configured and reconfigured

The M150 Measurement Platform is customer configurable with interchangeable standard parts and accessories optimized for specific
measurement needs. Its unmatched versatility can save customers tens of thousands of dollars on the purchase of separate measurement stations. The M150 helps customers solve device problems such as those related to power consumption, operating frequency, signal isolation, signal integrity and channel bandwidth.

The M150 Measurement Platform is designed for customers who are:
• Working in semiconductor fabs, yield departments, failure analysis, process engineering and device modeling;
• Working on process characterization of III-V compound semiconductors such as gallium arsenide, silicon germanium, and indium phosphide for RF, microwave and millimeter wave applications;
• Working with signal integrity issues on PCBs and high-speed interconnects;
• Working with emerging technologies to accurately position, navigate and view their analysis for applications such as lab-on-a-chip, microfluidics, organic transistors, polytec neurons, MEMS devices and other biostructures; and
• University labs around the world doing R&D on semiconductor devices and processors.
