Clock noise is one of the dominant noises in space-borne gravitational wave (GW) detection. To suppress this noise, clock noise-calibrated time-delay-interferometry (TDI) technique proposed. In technique, an inter-spacecraft tone transfer chain necessary to obtain comparison information two spacecraft, during which electro-optic-modulator (EOM) critical and used modulate laser phase. Since EOM sideband modulation process introduces extra it may limit experimental demonstration suppression effect further affect GW solve problem, significant put forward requirement test whether components meet or not. work, based on typical Michelson TDI algorithm fundamental detectors, analytic expression strictly derived, relaxing specification compared commonly rough assessments. Furthermore, a method provided experimentally commercial (iXblue-NIR-10 GHz) tested. The results show that can detection mission LISA whole scientific frequency bandwidth by taking optimal combination data streams.
