The @ RESET OUTPUT signal is input here to provide the phase reset
signal that establishes a new phase starting point for the output
signals.
If the instrument is configured as the Master controller, its
own
@ RESET OUTPUT signal must be routed back to this connector
for the instrument to function properly.

Power Splitters - Low loss power splitters must be used to provide
the necessary impedance match and signal distribution to each
instrument. Terminate any unused power splitter outputs with
a 50R
load. Recommended power splitters are listed in the specifications at
the end of this supplement.
Cable Length - Since phase delay is directly proportional to
conductor length,
the length of all cables should be the same when
they share a common signal from the Master controller. Cable length
from the Master controller to the power splitters is not critical; cable
length from the splitters to the instruments
is critical.
