  • Agilent: Spectrum Analysis Basics
    This application note is intended to explain the fundamentals of swept-tuned, superheterodyne spectrum analyzers and discuss the latest advances in spectrum analyzer capabilities. At the most basic level, the spectrum analyzer can be described as a frequency-selective, peak-responding voltmeter
  • Capacitor Testing Procedures
    will find the 60 Hz dielectric strength test adequate and relatively inexpensive. Jennings does not recommend DC testing being performed by the user because of safety considerations. If DC testing is performed, care should be taken not to exceed 60% of the peak test voltage rating of the capacitor
  • Introduction to LIVM Accelerometers
    to figure 5. For sinusoidal vibration input, it is convenient to read the output with a true RMS reading AC voltmeter. To convert this value to peak g’s, simply multiply by 1.414. Example: g’s peak + 1.414 x g’s RMS. and,. g’s peak-to-peak = 2.828 x g’s RMS. Shock Accelerometers. Shock accelerometers

    to characterize ac voltage and current waveforms is crest factor - the ratio of peak to RMS value. The crest. factor of a sine wave is . CF of a full-wave rectified sine is also , but a half-wave rectified sine is 2. The CF of a square wave is 1;. triangle wave 3. Low duty cycle pulse trains can
