  • PT 102: Low Frequency Vibration Measurements on a Compressor Gear Set
    The gear set on a critical turbo-compressor was monitored with a standard industrial accelerometer at very low frequencies. Severe vibrations at the hunting tooth frequency were found to be amplified by a compressor surge modulation. Diagnostic evaluation and repair effectively eliminated the surge
  • Setting Up FFT Span And Resolution
    The Fast Fourier Transform (FFT) converts time domain waveforms, acquired in an oscilloscope, into frequency domain spectra. This al-lows the oscilloscope to provide the same kind of information normally supplied by an RF spectrum ana-lyzer. The LeCroy WaveMaster TM Series oscilloscopes offer
  • Principles of lock-in detection and the state of the art
    , noise measurement units, impedance spectroscopes, network analyzers, spectrum analyzers and phase detectors in phase-locked loops. The fields of research comprise almost every length scale and temperature, such as the observation of the corona in full sunlight, measuring the fractional quantum Hall
