A low-distortion oscillator is necessary for testing today'sADCs (analog-to-digital converters) that have resolution higher than 20 ...

To test the oscillator circuit, I formed a loop at the oscillator’s output that matched the loop at the end of the Lecher line. Part of that loop is a 6.8 Kohm resistor, there so that the ...

As designed, the circuit tests most inductors for use in power supplies and many inductors for RF circuits. An inductance-test oscillator comprises two transistors and a few passive components.

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...

Like many people who repair stuff, [Learn Electronics Repair] has an oscilloscope. But after using it to test a motherboard crystal oscillator, he started thinking about how people who don’t … ...
