Intentional electromagnetic interference (IEMI) is a serious threat to the stable operation of computer and other intelligent terminal equipment. For testing research on IEMI, it is very important to build a stable and reliable test system model for accurate analysis of test data. In the time-domain test of IEMI, the z-domain discrete system transfer function is usually used to describe the response characteristics of the test system. However, with the change of sampling frequency, the parameters of the z-domain model should change accordingly, which leads to inconvenience in modeling the test system. In this paper, a δ-domain transfer function model of the test system is constructed by the transformation from z-domain. And the δ-domain model has better stability at high sampling rate and can be approximately equivalent to the system transfer function in the continuous-time domain.
