THE SIGNAL MARKERS
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.
The calculated frequency 1/
∆
t (primarily used for
the measurement of periods).
1. The voltage between two horizontal 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.

Determining the frequency of a signal
requires the measurement of a period. The
easiest way to do this would be by placing
the vertical markers either on two
consecutive peaks or two identical slopes of
a signal.
