Crystal Oscillator
There are three oscilloscopes currently available: an older optoelectronics Opto-7000 that is rarely used, a newer Mitronics MIC-1028, and a recently acquired used Tektronics 2236 oscilloscope purchased at Dayton in 2009, which features a built-in frequency counter. During a recent...

The crystal-controlled oscillator circuit is designed to provide a stable and precise frequency output, which is essential for various electronic applications, particularly...
15-65MHz circuit diagram of the third harmonic
A circuit diagram illustrating the reliability of crystal startup, with power consumption significantly lower than the maximum allowed for the crystal. The transistor Q1 can be one of the following: 2N918, 2N3564, 2N5770, BF180, or BF200. The inductor L1 is...
Crystal oscillator
The crystal is part of a feedback circuit connecting the collector to the base. A trimmer capacitor in series adjusts the point on the reactance curve where the crystal operates, allowing for frequency trimming. The capacitor exhibits negative reactance, enabling...
Mutiple Output Crystal Oscillator Sensor
The figure illustrates a multiple output crystal oscillator, which primarily consists of three gates of Al, four resistors, two capacitors, and a crystal. Resistors R1 to R4 offset two inverters within the linear range and are connected between pin 4...
Crystal-controlled signal source
This general-purpose signal source is highly effective for signal-tracing applications. The output level is adjustable, exceeding 1 Vrms into a 50 Ω load. It is compatible with nearly any crystal in the 1 to 15 MHz frequency range. Q1 operates...
Oscillator using crystal
Below are a couple circuits you can use to produce a 32.768 KHz square wave from a common watch crystal. The output can be fed to a 15 stage binary counter to obtain a 1 second square wave. The circuit...
