5.4 Crystal Oscillator Circuit Setup for Characteristics 

 
The following setup was used to measure the open loop voltage gain for crystal oscillator 
circuits.  The feedback resistor serves to bias the circuit at its quiescent operating point and 
the AC coupling capacitor, Cs, is much larger than C1 and C2.
