4.1.4 Display of the measurement principles ("MEASURE") from the keypad
Activates or deactivates display
of the window of the 20 automatic
measurements of the reference
trace.
Activates the 20
automatic
measurements of the
4 traces with
displacement by
"scrolling".
As default, the cursors are
activated with the automatic
measurements
.
Selects, from among the traces displayed, the reference trace for the automatic and manual
measurements; the reference channel is identified by a circle in the colour of the channel in the CHx
or Fx zone.
Activates or deactivates display of the
cursors
of the manual measurements.
In automatic measurement, the cursors cannot be deactivated.
The vertical and horizontal cursors can be moved on the touch pad using the stylus.
The measurements made in position T (period), "
dt"
(time difference between the two cursors), 1/dt
(difference as a frequency, in Hz) and "
dv"
(voltage difference between the 2 cursors) are reported
in the status area. A phase cursor Ph (in °) proposes a value for the angle between T and the
reference.
4.1.5 Adjusting the "HORIZONTAL" time base
a) from the keypad
Increases/ decreases the coefficient of the
time base
by successive presses (T/DIV).
After a Zoom, the "Z-Pos." adjustment modifies the
position
of the screen in the acquisition
memory
(upper part of the screen).
Activates or deactivates the horizontal
"
Zoom"
function
A waveform screen is displayed at the top
of the screen, with the zoomed portion in
the main zone.
As default, the zoom is around
samples at the centre of the screen, but
the zone can be moved.
A zone can be zoomed by tracing a
rectangle around the zone to be enlarged
using the stylus on the touch pad.
The sensitivity values, time base, and
horizontal and vertical positions are
recalculated automatically.
