4.1.9. AUTOMATIC measurements, from the screen
Opening of the "Automatic
measurements" Menu window of the
channel
Opening of the "Automatic
measurements" Menu window of the 4
channels

The measurements are made and refreshed on the selected reference trace. All
measurements that can be made on this trace are displayed. (- . - -) is displayed for
measurements that cannot be made.

The window is closed by pointing to

with the stylus.

All 20 measurements selected will be displayed in the status zone at the bottom of the screen,
on a ground the colour of the channel:


Measurement
conditions

The measurements are made on the part of the trace displayed on screen between
cursors T1 and T2.

Any modification of the signal entails an update of the measurements.
They are refreshed as the acquisition proceeds.

The accuracy of the measurements is optimum when at least two complete periods of
the signal are displayed.
