Ppm Accuracy Definition
the calculators below to convert between ppm and Hz. The equation for this relationship is, where ppm is the peak variation (expressed as +/-), f is what is frequency error the center frequency (in Hz), df is the peak frequency variation (in Hz), and 106 is 1000000 (e.g. one million). Enter numbers below as integers, decimals, or use scientific notation (for example, enter 1500 as 1500, 1.5e3, or 1.5E3). Convert ppm to Hz Enter f (Hz) Enter ppm (+/-) Variation, +/- df clock ppm vs jitter (Hz) Min Frequency (Hz) Max Frequency (Hz) Max - Min Period (sec) For example, 100 ppm of 100 MHz represents a variation in frequency of 10 kHz. The maximum and minimum frequencies are therefore 100.01 and 99.99 MHz, respectively. The change in period between these two frequencies is 2 ps (that is, 1/99.99MHz - 1/100.01MHz). Convert Hz to ppm Enter f (Hz) Enter max or min f (Hz) Variation, +/- df (Hz) ppm (+/-) ppb (+/-) = 1000×ppm Max - Min Period (sec) For example, if a center frequency varies from 100 MHz to 100.01 MHz, this 10 kHz frequency variation represents 100 ppm.

Run WinDaq and Begin Recording on Windows Startup » What's All This PPM Stuff? Data Logger > Products More times than not when talking to a customer about clock accuracy and I mention a spec in units of http://www.dataq.com/blog/data-logger/whats-all-this-ppm-stuff/ parts per million (PPM) the response is, "Huh? What's PPM?" Fair enough, but first some background: Behind every great clock there's a crystal, a piezoelectric device that vibrates at a precise and known frequency. There are other ways to generate frequencies (a resistor and capacitor combination is one of them), but none are more accurate. Many of our data logger products provide a built-in date and time clock that the instrument uses to time and date stamp recorded data. If you record temperature and humidity, for example, you'll be able to determine the date and time of occurrence to a precision that is determined by the accuracy of crystal that drives the date-and-time chip that's embedded in the instrument. For reasons known only to crystal manufacturers, crystal accuracy is speced in units of PPM. Lower PPM crystals cost more than higher PPM, and manufacturers like us who use crystals in our products make a price/performance judgement call and then simply spec time-and-date clock accuracy at whatever PPM number is associated with the choice. So how do you use PPM to put the figure into the context of your appli
