The user can perform measurements on a certain
signal by using the four moveable markers. This
can be useful when measuring the interval between
two points or the amplitude of any given peak.
The following indications will appear on the
screen :
1. The time interval between two vertical markers.
2. The calculated frequency 1/
∆t (primarily used
for the measurement of periods).
3. The voltage between two horizontal markers.
4. Small dots indicating relative marker position on
the complete signal.
THE SIGNAL MARKERS
The markers can be moved through the arrow
keys. Keeping the key pressed down will move
the marker quickly, pressing it briefly will move
the marker by 1 position. The “mark 1-2” key is
used to select the desired marker.
