You mean one equipment per output, right? Paralleling 50 ohm inputs will result in the wrong termination resistance for a cable. This may not be a problem for a 10 MHz sine wave, as long as the direct coupled emitter follower can handle the load. I have used networks where the devices are high impedance. The cable sees 50 ohms at both ends. Some test equipment has an optional 50 ohm terminator, for use as a high impedance device. Suppose I have 3 frequency synthesizers that have optional terminators. Are there any ill effects, except phase shift, from putting them all on the standard's output, if only the end one is terminated? Has anyone tried the high impedance distribution scheme? Seems like "simultaneously" would be relative, unless the distribution cables are all of the same length.
