The ET-140 shaker's compact size, long stroke, and lightweight armature make it well suited for modal as well as general vibration testing. Features include a rugged suspension system which minimizes test fixture requirements and related fixture guidance problems. The standard trunnion allows operation in any position from vertical to horizontal. It also facilitates bolting the shaker in place either with or without vibration isolation mounts.
BSWA SW466 Impedance Tubes can accurately measure sound absorption coefficients and impedance within a frequency range of 100 – 6100 Hz according to ISO or ASTM standards. They also support the sound transmission loss measurements based on the Transfer Function Method using four microphones. The tubes are specially designed not only to work with the cut samples, but also for direct use in the field. The small size and durable aluminum construction make it easy to be transported and used for estimating the properties of walls, ceilings, installed building materials, road surfaces, different ground surfaces, interiors of vehicles, etc.

The PDV-100 Portable Digital Vibrometer is a battery-powered digital vibrometer for field studies that enables non-contact measurement of vibrational velocities in the 0 to 22 kHz frequency range and provides digital signal processing with both analog and digital signal outputs. Its lightweight, robust design in a hermetically sealed housing makes this device a handy and practical tool, whether used as a battery-powered solution or together with a mains adapter. When combined with the high vibrational velocity resolution of 0.05 µm/s, the high level of linearity across the entire frequency range provides a sturdy and reliable mobile vibration analysis tool. The digital interface to data acquisition environments guarantees data quality even in critical environments with electromagnetic faults.

The LW126HF.151-9 provides an economical test system solution when higher frequency testing or transducer calibration requires the high frequency response of the ET-126HF shaker. This system offers full performance up to 14,000 Hz with operation at reduced force levels up to 20,000 Hz. This system is used for both general purpose testing and transducer calibration requirements. A voltage-proportional-to-output-current output signal is provided for modal test and other applications requiring force monitoring. Compact size, light weight and convection cooled components make this system a good choice for desktop applications.

The PCB Modally Tuned ICP instrumented impact hammer features a rugged, force sensor that is integrated into the hammer’s striking surface. “Modal Tuning” eliminates hammer resonances in the frequency range of interest from corrupting the test data, resulting in more accurate and consistent measurements. The force sensor provides a measurement of the amplitude and frequency content of the energy stimulus that is imparted to a test object. Accelerometers are used in conjunction with the hammer to provide a measurement of the object’s structural response due to the hammer blow. Items analyzed can include resonance detection, mode shapes, transfer characteristics, and structural health – such as crack and fatigue detection.

This is a feature-packed metallurgical microscope with an upright design and both transmitted and incident illumination. The episcopic illuminator includes removable polarizer and analyzer, as well as adjustable field and aperture diaphragms. The plan-achromatic optical system offers sharp, flat-field images with excellent color-correction. The Siedentopf head with dual diopters and high-eyepoint eyepieces provides a comfortable and adjustable viewing platform. There is also a dedicated 18 MP camera for simultaneous viewing and imaging.
Model 3390 Waveform Generator generates highly stable and accurate waveforms that allow you to create almost any desired shape. It uses direct digital synthesis (DDS) techniques to achieve this level of performance and functionality. The exceptional signal quality of the Model 3390 is a result of its high resolution, fast rise and fall times, and deep memory. This makes it the ideal solution for applications that use the 50MHz bandwidth and below.
