The Model 1088A tap is used to provide a decoupled, isolated output
signal to your system loads. The source impedance of this tap is
approximately 600 Ohms, and it will provide an open-circuit signal level
of 6.4V to 11Vp-p, depending on overall system loading and distance from
the clock mainframe.
Each tap provides 3750Vrms isolation from the distribution bus to the
load, as well as surge suppression and EMI filtering. The taps are
capacitively-isolated from the DC Bus monitoring current.
