Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo.

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

Vibration analysis systems are used for vibration testing and modal analysis, including the instrumentation to acquire data and/or analyze results.

Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency. They can provide the user with a clear and precise window into the frequency spectrum.

Test equipment and instrument rental services rent or lease test equipment for electrical, electronic, vibration, acoustic, dimensional, NDT, analytical, environmental, process, EMI/RFI, and other specialty testing, measurement or inspection applications.

Product and component testing services is the evaluation of a finished product or component through performance in electrical, life, environmental exposure, dynamic, ergonomic or other specialized tests.  Also testing to standards such as UL 489, CE or MIL-STD 810.

Surface profilometers are contact or non-contact instruments used to measures surface profiles, roughness, waviness and other finish parameters.

Form gages and form gaging systems are used to inspect parameters such as roundness, angularity, squareness, straightness, flatness, runout, taper and concentricity. 

Surface metrology equipment is used to measure the surface finish and/or geometry of engineering components. Surface texture and topology characteristics include surface roughness, contour, form, waviness and defects.

Acoustic and vibration test equipment repair services includes repair and other services for vibration, acceleration and acoustic test equipment, instruments and sensors.

Digital filters use digital signal processing (DSP) to perform numerical calculations on sampled values of a signal.

Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function.
