ERAVANT
Wide mechanical tuning bandwidth Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity designs to yield near full band frequency coverage. Unlike dual-tuner oscillators, frequency and power optimization are accomplished by a single micrometer. Furthermore, these oscillators can be modified into electrically tunable oscillators by replacing the micrometer with an electrical actuator. The wide tuning bandwidth of these oscillators offers a low cost, high performance means of signal generation, making them ideal test sources for labs and antenna ranges. While standard models offer a waveguide interface, a coaxial interface is also available. When used with a Gunn oscillator regulator/modulator (SOR series), these oscillators can produce AM or FM modulated signals for many test applications.

Thorlabs, Inc.
Welcome to Thorlabs; below you will find links to our selection of Motion Control products, a subset of our entire line of photonics products. Thorlabs’ motion control products are separated into manual and motorized linear and rotation stages, multiaxis platforms, actuators, and controllers. The manual and motorized stages can frequently be configured into 1-, 2-, or 3-axis solutions. Since many of the stages are available in either manual or motorized versions, creating a custom system is easy. For nanopositioning applications like waveguide and fiber coupling, our line of multiaxis flexure stages are ideal. Both the motorized stages and the multiaxis platforms are supported by a complete line of controllers for the various motors and piezoelectric actuators. In addition, we support custom and OEM motion control applications with an extensive line of manual, motorized, and piezo actuators as well as threaded adjustment screws.

Fairview Microwave Inc.
Fairview Microwave’s line of coaxial RF probes and RF PCB probe positioner are ideal for use with chip evaluations, signal integrity measurements, coplanar waveguide, substrate characterization, gigabit SERDES and test fixture applications. The RF coaxial probes provide return loss better than 10 dB and a maximum operating frequency of 20 GHz. The probes have a 3.5mm female interface, a pitch of 800 or 1500 micron and they can be cable-mounted. They feature gold-plated contacts and can be used by hand, with or without a probe positioner. Compliant coaxial GSG (or GS) pogo pins allow for a broad range of probing angles. The RF PCB probe positioner can hold coaxial probes, has articulated joints and delivers multi-axis positioner control. This positioner also boasts a magnetic mounting plate with on-off positioner switch.

IST Engineering, INC.
With at-speed test, debug can easily become a problem: If test points are on the bottom, as is often the case for test processing, then this requires the board to be flip over for the debug. However, during at-speed testing, key devices and signal paths are often on the topside. IST Engineering has in-house expertise with debug fixtures, which allow the test technician to flip over a test board, or even hold it vertically for dual-sided access, while still running the Device-Under-Test at full-speed through card-edge connectors - whether these are standard DIN type or F or N type co-ax connectors. The debug stations are constructed robustly, with metal frames and high-grade flexible cabling and can also be used as backup test stations in a manufacturing flow. They can be built with custom machined waveguide connections for RF/Microwave applications, or with standard, off the shelf connectors, as defined by the application. A number of these debug fixtures are in production use with a range of customers.

ERAVANT
Is a dual function direct reading and programmable rotary vane type attenuator for use in millimeterwave systems across the standard WR-03 frequency range of 220 to 330 GHz. The attenuator is an ideal piece of equipment in waveguide systems where a broad direct reading of attenuation is required. The default mode of operation is manual direct reading. In manual mode, the attenuation is adjustable with the large knob and the digital LCD screen displays the current attenuation value. The LCD screen is powered by an internal rechargable battery, which is charged via the 2.5mm DC jack by a provided DC to AC adapter. The 2.5mm DC jack also provides power to the stepper motor, encoder and internal microprocessor for the programmable mode function. The user can quickly switch to programmable mode by connecting the powered-up attenuator to a computer with the USB Type B port. In programmable mode, the attenuation is finely adjusted with a precision stepper motor by the internal microprocessor via user-entered serial port commands from the computer.

Torontech Group
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.
