Greenray Low g-Sensitivity Oscillators
The "g-Sensitivity" of an oscillator is a measure of how much the frequency changes due to exposure to an acceleration event, and is typically denoted by the Greek letter gamma "Γ." Γ is often evaluated under a particular level of vibration, but it is important to note that frequency shifts can also occur due to a shock pulse or sometimes even due to normal handling.
If an oscillator experiences any level of vibration during normal operation, the effect on spectral purity (phase noise) may be significant. Regardless of how low the phase noise of an oscillator may be at rest, phase noise under vibration will be determined primarily by the unit's g-Sensitivity. Knowing the g-sensitivity of an oscillator, the nominal frequency and the applied vibration level makes it possible to calculate the resulting phase noise. Calculations will determine what g-Sensitivity is required to meed a specific phase noise level under expected levels of vibration.
