Most ISO-MAX isolators use 1:1 transformers that simply reflect the load connected to their output back to the driving source, so there is no additional “loading” of the source. Because the copper wire used in transformer has resistance, a small signal loss is unavoidable. When used as directed, this “insertion loss” is generally under 1 dB for most isolators. However, some special-purpose isolators (PC-2XR and DB-2PX, for example) intentionally change signal level and impedance.
