WebNov 28, 2024 · The frequency accuracy of the GPSDO is essentially that of GPS, plus or minus the short term stability of the crystal oscillator. In other words, a properly operating GPSDO is probabably accurate to parts in 10 -13, and if you measure it once per day, those measurements will be constant at about that level. WebMar 6, 2015 · The frequency will also tend to drift over time, an effect that is often specifed as "aging". This effect is also beyond what's specified for initial accuracy. For example, the part linked in the other question mentioned in Eugene's comment, FX135A , has an initial accuracy of +/- 20 ppm, but it will drift as much as +/- 3 ppm per year due to ...

Different countries/utility companies have their own philosophies in implementing the under frequency load shedding scheme. Generally, it …
In electrical engineering, and particularly in telecommunications, frequency drift is an unintended and generally arbitrary offset of an oscillator from its nominal frequency. Causes may include component aging, changes in temperature that alter the piezoelectric effect in a crystal oscillator, or problems with a voltage regulator which controls the bias voltage to the oscillator. Frequency drift is traditionally measured in Hz/s. Frequency stability can be regarded as the absence (or a very lo… WebOverall, the students’ daily activities, motivation, interpersonal interaction, self-confidence, and anxiety behaviors improved; (4) Conclusions: After the 8-week step program, the participants with intellectual disabilities improved their step frequency, movement stability, ability to perform daily activities, walking speed, motivation ...
