Horizontal offsetting of the trace
Adjustment of the time base according to the frequency of the input
signal to be observed. 19 calibrated positions from 100ns to 0.1s/div.
Continuous adjustment of the scan coefficient by a factor of 1:1 to
1:2.5. When the button is locked against the stop on the right, the time
base is calibrated.
Selection of the trigger mode
Automatic or "relaxed" time base mode.
The trace remains visible, even if no event triggers the oscilloscope.
Normal or "triggered" time base mode
A trigger event must be present for the trace to be visible on the screen.
Selection of the trigger source.
Trigger mode for video or TV signals.
Recommended scan coefficients between 0.5 and 200µs/div.
Synchronization by the frequency of the mains power supply.
Correct triggering is obtained if the signal presented on Y INPUT [9] is
composed on the basis of the mains (50 or 60Hz).
Synchronization by an external source connected to the TRIG terminal.
EXT [20].
Selection of the trigger slope.
Trigger on rising signal slope
Trigger on falling signal slope
When the switch is set to XY, the signals connected to the Y INPUT [9]
and X INPUT [20] inputs are displayed using orthogonal coordinates,
vertically for (Y) and horizontally for (X); the time base is inoperative
and the sensitivity adjustment [8] is common.
The most frequent uses involve Lissajoux figures, characteristic of the
types of components.
Adjustment of the trigger level; reduction of the level clockwise, increase
of the level anticlockwise.
