CONVI 103

The CONVI 103 is a standard converter that accepts in input a serial digital signal ITU-R 601 (SDI) and converts this into various analog formats available on the  4 output BNC. To optimize use, it provides 2 regenerated SDI outputs.
At conversion level, it features a fixed PAL standard output and 3 outputs that can be programmed using dip-switches which alternate RGB, or YUV, or YC plus a second PAL output.

  • 1 digital input ITU-R 601 (SDI) terminated at 75 ohm
  • 2 regenerated and reclocked digital outputs

  • 1 fixed PAL analogue output

  • 3 programmable analog outputs

  • Internal TEST generator on all the outputs

  • Possibility of disabling the color

  • Possibility of synch. insertion in RGB

  • 2 selectable internal digital filters

  • Output level adjustment using trimmer on front panel
