.01 % = 100 PPM
.005% = 50 PPM
.001 % = 10 PPM etc.
As frequency tolerances are tightened, costs increase incrementally. An Oscilent standard frequency tolerance is ±30 PPM.

| Frequency Tolerance | ||
| The deviation from
the nominal frequency expressed in Parts Per Million (PPM) at room temperature
(+25°C) Frequency tolerance is sometimes expressed as a percentage of frequency
deviation, rather than as Parts Per Million (PPM) The conversion is as follows: .01 % = 100 PPM .005% = 50 PPM .001 % = 10 PPM etc. As frequency tolerances are tightened, costs increase incrementally. An Oscilent standard frequency tolerance is ±30 PPM. |
