Definitions
Random Uncertainty
The RSS of all random or Type-A measurement errors expressed as the total RMS or 1-σ measurement uncertainty. Random
uncertainty will reduce as 1/√N when averaging N measurement results for up to a maximum of approximately 13-digits or 100 fs.
Systematic Uncertainty
The 95% confidence residual constant or Type-B measurement uncertainty relative to an external calibration reference.
Generally, systematic uncertainties can be minimized or removed for a fixed instrument setup by performing relative measurements to
eliminate the systematic components.
Timebase Uncertainty
The 95% confidence systematic uncertainty contribution from the selected timebase reference. Use the appropriate uncertainty for the
installed timebase or when using an external frequency reference substitute the specified uncertainty for your external frequency
reference.
