using cursors
•
Select measurement by cursors using the menu:
Measure Manual measurements (dt, dv) (see §. Measure Menu).
∗
Two measurement cursors (1 and 2) are displayed as soon as the
menu has been activated.
∗
The 2 measurements indicated under the trace display are
dt (interval between the 2 cursors as a function of the time base) and
dv (voltage between the 2 cursors as a function of the vert. sensitivity).
Example: (1)dt : 2,150 ms, dv = 250.0 mV
