Crystal Oscillator Measurements
On the Data Collection System, there are several crystals. For this test a crystal is multiplexed
into the device circuit, and the crystal’s capacitance values can be varied. The capacitance and
voltage values are varied to determine the best characteristics (current, oscillator waveform, and
oscillator start-up), and then the currents are measured over voltage. The next crystal oscillator
is then switched in and the procedure is repeated.
