The side-screen Cursor menu now shows:
•
The voltage at
Cursor 1
.
•
The voltage at
Cursor 2
.
•
Delta
shows the voltage difference between the two cursors, which is the desired peak-
to-peak voltage measurement.
Now, suppose you want to measure the time between two events displayed on the scope.
Again, you will use the upper knobs in the Vertical Controls section to set the positions
of the cursors. Proceed as follows:
1. Push the
CURSOR
button to see
the Cursor menu.
2. Push the top menu button to
select
Time
.
3. Push the Source menu button to
select
CH1
.
4. Use
the
CURSOR 1
knob to place
a cursor at the start of the time
period to be measured, as shown
in Figure 8.
5. Use
the
CURSOR 2
knob to place
the remaining cursor at the end of
the time period.
The side-screen Cursor menu now
shows:
•
The time at
Cursor 1
.
•
The time at
Cursor 2
.
•
Delta
shows the time difference,
which is the length of the period,
and the frequency (reciprocal of
the period).
