Claim 15:
16. The device according to claim 15, wherein when determining first offset parameters of the first DUT in the plurality of DUTs, the one or more programs cause the one or more processors to execute operations of:
determining in the first time parameters a plurality of critical TISs corresponding to each TCK signal with corresponding frequency; wherein when the first DUT receives the test signal with the TCK signal with one frequency, the sub-information corresponding to the TIS greater than the critical TIS is in the first state, and the sub-information corresponding to the TIS less than the critical TIS is in the second state; and
obtaining the first offset parameters based on a difference between the plurality of critical TISs corresponding to each TCK signal with the corresponding frequency in the target time parameters and the plurality of critical TISs of each TCK signal with the corresponding frequency in the first time parameters.
