Nice thread on your SMG40 btw. The spec is proper state-of-the-art. We used to use one of those to check FM rebroadcast receivers. In order to achieve cross-talk in excess of 50dB at 15kHz, the multiplex timing /group-delay error has to be below c.100nS if I remember correctly. Quite onorous for an "audio" signal !
