About QuartzCrystal Oscillator Prof

QuartzCrystal Oscillator shows the impedance / admittance characteristics of quartz crystals over frequency. An external circuit capacitance and an additional series impedance can be put in series to the crystal to evaluate the behaviour in practical circuits.

Switching the structure to 'Pierce/Colpitts Oscillator' allows to evaluate and optimize these popular oscillator configurations, which are used with most processor units. Doing so, the vastly very general manufacturer recommendations can be optimized improving startup time and providing for acceptable crystal power values. A program-controlled optimization routine is provided.

Minimum requirements: Android 4, smartphone / tablet with 5' - display or bigger

Features:

Three structure modes: Quartz Crystal and Pierce/Colpitts Oscillator

Crystal mode:
Series and load resonant crystals
Crystal equivalent parameters variable
Impedance display as well as admittance display
Additional spurious resonance possible
Additional Nyquist diagram possible

Pierce/Colpitts oscillator mode:
Shows transfer function of Pierce/Colpitts feedback network
Allows to optimize feedback
Shows circuit values for 3rd harmonic crystals
