Metrology and You

  • Do I need to worry about all of this? (as a hobbyist, is accuracy important?)-
  • Measure with micrometer...
  • Taking Measurements
    • voltage, current, resistance, inductance, capacitance, Q, frequency, time, noise, RF/microwave
    • Measurement Uncertainty
      • +/- 0.1dB specification - what can go wrong?
  • How do you make things more accurate?
    • System engineering - when the boards are put together, does the system work?
    • Testing the idea that multiple resistors are tighter tolerance than single
      • Are the values random?
    • Sources of errors - narrow things down to the path between a sensor and an ADC
      • Temperature
      • Noise, thermal
      • Noise, switching power supply, rectifier diodes
      • Noise, clock, data, address
      • DC shift - where does the ground current flow? Screws, contact resistance, and X-Acto blades.
    • Offset voltage and current
  • Connector Repeatability
  • Temperature
    • Repeatability/Skid
    • Controlling temperature (room air, coffee cup, fingers, oven proportional control)
