2.17 LBAL - Longitudinal Balance
longitudinal balance test is Voltech's preferred method to measure what is
effectively the Common Mode Rejection Ratio of a transformer designed to
connect to a balanced line.
measurements are performed each by applying a voltage to the transformer
and measuring the resulting voltage to calculate the CMRR.
This test is suitable for audio and telecommunication transformers and
checks the effective common mode rejection ratio of the transformer.
