The SIM 3 Hardware
2.4.6. Using Multiple SIM-3004 Remote Power Supplies in a System
Larger SIM 3 measurement systems may require the use of multiple SIM-3004 units to power
the various switchers. Remote power supplies are used to supplement the power that is
supplied by the analyzer itself.
The remote power supply will provide DC current to switchers connected to the right-hand
connector, and will pass audio signals to the analyzer and control signals from the analyzer.
As long as an unbroken signal path exists through the connecting cables, SIM-3004 power
supplies may be inserted between every two SIM-3088 line-level switchers and every one
SIM-3081 mic switcher, up to the maximum number of switchers that can be supported by
SIM 3.
