External Modulation
54200 allows external video and sound modulation by an external CVBS signal respec-
tively sound signal so the instrument is used as an RF modulator.
External Video Modulation
In the External Video mode the vision carrier can be modulated by an external video sig-
nal (VBS or CVBS), whereby the nominal amplitude should be 1 V pp with a positive
going polarity. The maximum permissible input voltage is
ñ
5 V (peak-peak + dc).

Remarks/ Function
SCART EURO AV IN
(rear)
Source for video outputs is the SCART connector.
Source for video modulation of the vision carrier is
the SCART connector (Pin 20, CVBS).
BNC VIDEO IN
(front)
Source for video outputs is the selected video input.
Source for video modulation of the vision carrier is
the VIDEO IN connector.
SCART Mixed EURO AV IN
(rear)
Source for video outputs is the internal video signal.
Source for video modulation of the vision carrier is
the SCART connector (Pin 20, CVBS).
BNC Mixed VIDEO IN
(front)
Source for video outputs is the internal video signal.
Source for video modulation of the vision carrier is
the VIDEO IN connector.
For the internal video modes the external applied video signal must not be switched off
or removed.
