2.1 Test Standards

The tests in this application note are performed in accordance with the following standards and procedures.

  • Random Vibration: MIL-STD-883F standard: Method 2026C
  • Mechanical Shock: MIL-STD-883F standard: Method 2002.4B
  • Sinusoidal vibration at 10 g with vibration frequencies of 50, 100, 200, 500, 1000, and 2000 Hz

Phase noise and jitter performance are recorded before, during, and after the random vibration, following the preceding MIL (Military) standards. Frequency drift is recorded as per the mechanical shock standard test setup. Sinusoidal vibration at different vibration frequencies is conducted and based on the phase noise result, the ppb/g value is calculated for the BAW oscillator. The test setup, procedure and test results are provided in later sections of the document.
