bsw TestSystems & Consulting AG
Especially for signal generation above 50GHz and in waveguide bands is done with a standard lower microwave generator and then the signal is frequency multiplied to get to higher frequencies. The frequency multiplied signal may optionally be filtered to make it spectrally pure and/or amplified to come to an appreciable signal level.

VisualIMPACT Software
-
CEAST VisualIMPACT software is designed to control CEAST Pendulums and Drop Tower Series, manage tests and offer a user-friendly interface when using the Data Acquisition System. It records force and absorbed energy data related to impacts, visualizes and helps analyze the results and calculates resilience. The operator is guided through parameters setup by means of tables describing strikers and specimens that are filtered according to the test type and international standard selected. In the case of instrumented tests, many possibilities for data analysis and visualization are made available. The results are shown through comprehensive and customizable graphs and can be filtered by break type (only specimens with a selected break type are shown). Working with groups of test, the software performs a statistical analysis, and the operator can pick and discard single test results. Different measurement units can be selected. It is possible to print reports and to export data totally or partially. Recent improvements include the possibility to set a number of user profiles, including graphic settings, default printing options, advanced parameters for data analysis and so on, switching quickly from one another when looking at results. The introduction of a new Data Acquisition System (CEAST DAS 64K) in the Impact product line has also triggered a number of new capabilities for the SW, which is now able to process a more comprehensive calibration file for instrumented tups and hammers and manage DAS configurations with a wider range of data acquisition channels.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.

High Temperature Axial Torsional Extensometers (1200 C or 1600 C)
Model 7650
-
Jinan Testing Equipment IE Corporation
Model 7650 extensometers are primarily used on round specimens tested in bi-axial test machines capable of simultaneous axial and torsional loading. All models are capable of bi-directional displacement in both axes and may be used for strain-controlled fatigue testing under fully reversed load and strain conditions at frequencies up to 10 Hz.All 7650 models mount rigidly on the load frame and incorporate slide mounting to bring the extensometer into contact with the specimen. The gauge length is set automatically before mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.These units are specifically designed to minimize crosstalk between axes and to provide high accuracy, high resolution measurements. They incorporate capacitive sensors for low operating force and include electronics with programmable filtering and multi-point linearization for improved performance and accuracy. The overall design minimizes, and in many cases virtually eliminates, any influence from common lab environment vibrations.These water-cooled extensometers are equipped with high purity alumina rods with conical rod tips for specimen contact when testing to 1200℃(2200°F). Silicon carbide rods are used for the 1600℃ (2900°F) high temperature option.

High-Power Tunable Filter
CB503
-
The need for tunable filter technology originates from the fact that high power communication systems and IED Jammer transmitters severely limit the use of tactical radio communication systems on the battlefield.This clash within the radio’s spectrum during tactical missions is often de-conflicted using fixed high Q, high power RF bandpass and bandstop filters installed prior to mission. This can limit operational effectiveness due to the potentially large number of fixed filters required within the allocated radio communication channels, which need be transported, stored in the field, and fitted by trained personnel. Many of these fixed filters centred within the octave wide tuning range could be replaced by a single high-Q tunable filter.
