Global Invacom dSCR GTU

The D000199 dSCR GTU converts optical power to RF power (4 satellite bands and FM, DAB, DTT). Terrestrial signals are overlaid onto both output ports. All units have built in AGC which allows a wide dynamic range of optical levels without affecting output power and quality.

Product code: D000199

This is an alternative product to the standard Quad GTU. The dSCr GTU has auto syncing outputs and is therefore compatible with legacy and SATCr decoders. It does not require the external MUDS switch when a SATCr decoder such as Explora us used.

Each output can operate as Legacy, SCR automatically detects which box is connected
and sets itself up accordingly. Terrestrial signals are available on each output if used in an ODU32 system

  • Optical to RF convertor (Satellite and FM,DAB,DTT )
  • Automatic Gain Control (AGC)
  • Terrestrial signals overlaid onto each output

The dSCR GTU converts optical power to RF power (4 satellite bands and FM,DAB,DTT ). All units have built in AGC which allows a wide dynamic range of optical powers without affecting output power and quality. One LED indicator allows the user to monitor the status of the unit. Configurable for any user bands. Able to work in legacy, analogue SCR (aSCR) and digital SCR (dSCR) modes.
