Kenwood CS-5200 Series - Composite Video S I G N a L D I S P L a y

DC : DC coupled trigger signal is input to the trigger circuit. This position is
used for low-frequency signals below 10 Hz.
TV FRAME: Vertical synchronization pulses are extracted from the composite video
signals and input to the trigger circuit.
TV LINE : Horizontal synchronizat ion pulses are extracted from the composite video
signals and input to the trigger circuit.
• Trigger mode
Select an intended trigger mode.
AUTO : Operat ion runs free and the trace 1ine appears even if there is no trigger
signal. Use NORM to observe low-frequency waveform below 40 Hz.
NORM : Sweep operation is executed according to the trigger signal. Sweep operation
is not executed if there is no trigger signal.
FIX : Sweep operation is executed according to the center of the amplitude of the
trigger signal as the trigger point. In this mode, the trigger level need not
be adjusted.
SINGLE: Selects the single sweep mode. (See 7-6)
RESET : Sets the oscilloscope for triggering in the single sweep mode. (See 7-6. )
3) Composite video signal display
When inputting composite video signals, set the COUPLING control to either TV FRAME or
TV LINE. Also switch the SLOPE control in accordance with the signal polarity.
