G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation

Dual Channel Clock Driver Card
PI-41400
-
The PI-41400 is a dual channel Clock Driver card capable of operating up to 190 MHz into a 50-ohm load and up to 80 MHz at an amplitude of 8 volts into a 1-megohm load. Into a high impedance load the output voltage range is from a –3 volts to 8 volts with the output pulse amplitude ranging from 0.5 V to 9 V. When driving a 50 load the voltage range is –1.5 volts to 4.5 volts with the output pulse amplitude ranging from 0.25 V to 4.5 V. The rise and fall times of the output pulse are variable from 1.2 ns to 9 ns into a 50-ohm load and <5 ns to 9 ns into a HiZ load. The output pulse amplitude and the load being driven determine the range of variability. The driver output can be set for tri-state operation and the output polarity can be set for ‘Normal’ or ‘Inverted’ operation through software.

32 Channel Optically Isolated Digital Card
104-IDIO-16 Family
-
The Model 104-IDIO-16 is a 32-channel PC/104 utility board featuring 16 optically isolated inputs and 16 optically isolated solid state outputs. The isolated, non polarized inputs may be driven by either DC sources of 3-31V (or higher by special order) or AC sources at frequencies of 40Hz to 10KHz. Optically isolating the digital inputs from each other, and from the computer, assures smooth, error-free data transmission in noisy, real-world environments. The 16 input channels are available via a 34-pin IDC type header. The fully protected solid state outputs, capable of sourcing 2A each, are inherently more reliable than electromechanical relays and give system architects a more robust product to design with. The solid state outputs are available via a 50 pin IDC type header.

Flame Ionization Detector
-
A flame ionization detector converts a hydrocarbon gas concentration into an electrical signal. The flame is hydrogen fueled and burns in hydrocarbon free combustion air. Either side of the flame are two electrodes between which an electric field is generated by means of a polarization voltage. The sample is pre-mixed with the fuel gas and heated in the flame to a temperature at which the hydrocarbon molecules ‘crack’ and CH fragments appear. These CH fragments are oxidated by the oxygen in the combustion air resulting in the formation of CHO+ ions. The ion current then passes to the electrodes and the resulting current measured is proportional to the quantity of C atoms derived from organic compounds.The Thermo-FID features two separate microprocessor controlled pressure compensations to avoid any influence from environmental or sample conditions. In addition, the complete Thermo-FID range of analyzers are equipped with a flame trap that is used as a heated sample inlet filter. The measurement chamber and all material in contact with the sample gas are heated between 120°C and 200°C to avoid condensation.

Controller
Optimizing DC bias points of an IQ modulator is no trivial task. There are six different Mach-Zehnder structures inside one dual polarization IQ modulator, all simultaneously influencing the properties of a single optical signal. Trying to optimize bias points using just the intensity measurement of the optical signal is time consuming, inaccurate and it requires a lot of knowledge and experience.

Audio Fiber Tracer
CFT-810

Motorized Polarization Controller. In addition to its basic function of adjusting polarization states in multi channels, it also provides convenient ‘save and recall’ functions. As a Scanning PC, it provides very powerful ‘auto scan’ modes with variable scanning speeds. Polarization states can be manipulated by either manual adjustment or remote control (GPIB, RS-232) using two quarter-wave plates in each channel of the PC1600. Additionally, the auto scan mode of FIBERPRO’s Motorized Polarization Controller has been upgraded in LPC, and it shows another auto scan mode of four quarter-waveplates with higher polarization extinction ratio when connecting two channels at a high speed. PC1600 is an essential tool to complete fiber-optic, multi-channel measurement systems such as WDM/DWDM as well as R&D (i.e. PMD experiments), and manufacturing.

Microscopes offered by Buehler generally fall into the categories of stereo microscopes, upright microscopes, or inverted microscopes. Inverted microscopes are commonly referred to as metallurgical microscopes. Microscopes may offer episcopic (reflected light) observation, diascopic (transmitted light) observation, or both possibilities. Illumination may be delivered in bright field mode (BF) or dark field mode (DF), and several techniques such as differential interference contrast (DIC) and polarized light microscopy make use of the nature of light to reveal specific pieces of information when studying materials.
