  • Hardy Shaker

    HI-903 - Metrix

    This is our top of the line Hardy Shaker. It provides the ability to set the amplitude and change the frequency range without the amplitude changing. This automation makes conducting vibration tests easier. Tests can be conducted on multiple vibration transducers, and then the saved data can be transferred via USB Flash Drive to be displayed in an automated and customizable report using an Excel template on your computer. In manual mode, the vibration test level and test frequency can be set from 7 Hz to 10,000 Hz. The high accuracy instrument can display the vibration level in terms of g’s peak, velocity peak (in/sec or mm/s) or displacement peak-to-peak (mils or µm). The unit can support payloads up to 800 grams (see frequency limits in the manual). A built-in display reads the output sensitivity, which can be stored in memory. Complete testing sequences and data can be stored in memory for each tested sensor, the unit logs the data on the spot or stores it for later use. For testing of heavy transducers or at high frequencies, the HI-903 automatically corrects the sensitivity calculation for the effects of transducer mass loading. A built-in self-test program checks for accuracy of all calculations. The HI-903 has a built-in battery charger that can operate on 120 or 240 VAC. The unit comes in a rugged Pelican case.

  • Preamplifiers

    Com-Power Corporation

    Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.

  • PXIe Audio Analyzer

    M9260A - Keysight Technologies

    M9260A is significantly different from the traditional general purpose PXI digitizer modules which are being used for today's audio measurement. In order to achieve fast test speed and high performance it comes with large one million sample arbitrary waveform buffer and one million sample "limitless" input buffer, as well as super-linear/low noise amplifiers and digital to analog converters. This enables M9260A's ultra-low residual distortion and high amplitude accuracy. M9260A is now an important part of Keysight Radio Test Solution, and may also be easily integrated into any audio related PXI test system with its developer-friendly drivers and commands.
