What Methods Are Used for Measuring Phase ?
  • A 'Phase-Triggering' Strobe Light. This type of strobe light differs in two ways from a conventional, hand held strobe light:
    • It either feeds frequency information (its flash rate) into the analyzer or has its flash rate set by the analyzer.
    • It can be triggered by a vibration signal from the analyzer.
  • A Photoelectric Eye (or related mechanism that provides a 1x rpm pulse from the shaft).
