transformer loss

transformer loss

[tranz′fȯr·mər ‚lȯs]
(electricity)
Ratio of the signal power that an ideal transformer of the same impedance ratio would deliver to the load impedance, to the signal power that the actual transformer delivers to the load impedance; this ratio is usually expressed in decibels.

In this case, a 250:50 [ohms] impedance transformer is required for each output port and an extra measurement is required to measure the transformer loss for each output port in addition to the port's insertion loss/gain measurement.
