This product has reached end of life and is no longer available. Please contact Digisat for a suitable replacement from Quintech.
The RSS175024X24NE000 is a 2-to-24 substitution switching system that provides solid-state L-Band switching for a single set of antenna modulators (up to 24 per antenna). It offers 24 sets of primary inputs and outputs as well as two auxiliary modulator inputs, each one of which can be substituted for any one of the 24 primary inputs. Control and status is provided either locally via the front panel keypad or remotely through a serial or Ethernet interface. Each of the primary modulator paths through the switch have guaranteed "zero-loss" whereas the auxiliary modulator (substitution) path has an additional 3.5 dB gain to compensate for the external power divider loss. Any non-selected paths are internally

Features & Benefits
Greatly enhances flexibility in operations by substituting any of the 24 output signals with either of the two auxiliary inputs
Ideally suited for teleport or uplink applications requiring the highest level of signal integrity & flexibility
Auxiliary ports ideally suited for redundancy and test applications
Auxiliary ports is internally terminated automatically when in substitution mode
