MEP EP#293: Tom Anderson, the Gold Ear SympatheticTom Anderson An old-timer engineer working from HP/Agilent/Keysight Currently still employed at Keysight Volunteering at Alembic, where he designs electronics for bass guitars Career includes: Design of firmware Digital Analog Microwave Optical Power supplies Software Information systems 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, switc
