Electronic Instruments
Basic electronic instruments found in a typical laboratory workbench. The DC
power supply is used to provide current and voltage to electronic circuits. A
function generator is used to produce electronic signals. If you want to observe
and measure these electronic signals an oscilloscope is needed. The most
useful tool of them all is the digital multimeter used for measuring voltage,
current, and resistance.
