| Keysight | 53131A/132A/181A Counters - Data Sheet Auto arming Measurements are initiated immediately and acquired as fast as possible, using a minimum number of signal edges. Timed arming The duration of the measurement is internally timed to a user-specified value (also known as the “gate time”). Digits arming Measurements are performed to the requested resolution (number of digits) through automatic selection of the acquisition time.
| Keysight | 53131A/132A/181A Counters - Data Sheet Fractional time base error (see Graph 3) Time base error is the maximum fractional frequency variation of the time base due to aging or fluctuations in ambient temperature or line voltage: Time base error = ( ∆f f Aging rate + ∆f f Temperature + ∆f f Line voltage ) Multiply this quantity by the measurement result to yield the absolute error for that measurement. Averaging measurements will not reduce (fractional) time base error.
| Keysight | 53131A/132A/181A Counters - Data Sheet Differential channel error The differential channel error term stated in several systematic uncertainty equations accounts for channel-to-channel mismatch and internal noise. This error can be substantially reduced by performing a TI calibration (accessible via the utility menu) in the temperature environment in which future measurements will be made. Graph 1: 1E + 02 The graphs may also be used to compute errors for period measurements.
