The Leading Measurement System for the Analysis of Porous Materials

ELWIS

Autoneum Holding AG

ELWIS - Autoneum Holding AG

ELWIS (Evaluation of Light Weight Impedance System) offers a full and rapid characterization of porous materials based on the analysis of a single sample. The ELWIS system consists of the ELWIS-A and ELWIS-S components which can be used independently from each other although both applications are needed for a complete material simulation.ELWIS-A measures acoustic parameters that are needed to evaluate the acoustic performance of sound insulation and sound-absorbing multi-layer materials. An additional impedance tube for absorption measurements at higher frequencies is available for ELWIS-A.ELWIS-S measures structural parameters that are needed to simulate the dynamic and acoustic behavior of sound packages in the medium to low frequency range (including the "Poisson Ratio" for foam materials).ELWIS is very easy to operate: Thanks to its user-friendly software, the system can also be used to obtain reliable results by users with only limited experience in the characterization of porous materials.

MixAMC-I - Virginia Diodes, Inc.

Virginia Diodes'' standard Spectrum Analyzer Extension Modules (SAXs) provide high performance broadband down-conversion and frequency extension of microwave specturm analyzers into the THz range. VDI now offers integrated MixAMC modules that provide industry leading performance in a compact package. These integrated MixAMC modules are used to down-convert millimeter-wave / THz signals only. Spectrum Analyzer Extension mode is not currently available for the MixAMC-I products. Integrated MixAMC modules utilize a low frequency LO input (<20 GHz) and have a seprate IF output port. Integrated MixAMC modules configured for high IF bandwidth may be available upon request.

HUM DETECTOR (DEMODULATOR)

HD-500

Matrix Test Equipment Incorporated

HD-500 - Matrix Test Equipment Incorporated

The MATRIX Model HD-500 is a detector-amplifier designed to demodulate the low frequency amplitude modulations on any RF carrier over the range of 5 to 1500 MHz. These modulations are usually the undesirable result of the 50 or 60 Hz power source and are not necessarily sinusoidal. The unit is calibrated to the SCTE definition of hum modulation, which is the ratio of the peak-to-peak hum modulation to the peak of the carrier.

500 MHz Passive Probe, 2.5mm, 10:1, 10 MOhm

Teledyne LeCroy

PP022-1 - Teledyne LeCroy

Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a 10:1 attenuation and feature a high input resistance of 10 MΩ. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to handle voltages of at least 400V, some as high as 600V. Teledyne LeCroy passive probes feature an attenuation sense pin which tells the oscilloscope to scale the waveforms automatically requiring no user input.Each passive probe is recommended for a certain oscilloscope, using the right passive probe with the right oscilloscope means that the probe will be properly compensated across the entire bandwidth. Using probes with a different oscilloscope will only let you compensate for low frequencies.
