Note1: Refers to the time from booting to reaching the performance index.
Note2: The bias stability and the random walk coefficients are measured by the allan variance analysis under the laboratory steady temperature conditions.
Note3: The GJB-2426A method is used for statistics, and the relevant time is 10s.
