3.12 CURSOR OPERATION
Cursors are used for accurate amplitude or time measurements of the signal.
Step 1 Before you continue, reset the instrument with the STANDARD
SETUP. To do this, press the
STATUS
key and
TEXT OFF
key
simultaneously. Now the instrument is set in the default condition and
operates in analog mode.
Step 2 Press the
AUTOSET
key.
Step 3 Press the
CURSORS
key to enter the cursors menu.
The menu is now displayed on the screen and the
cursors are turned on.
Step 4 Use the second blue softkey from the top to select
one of the three cursor modes:
- Amplitude cursor measurements, indicated by ’=’.
- Time cursor measurements, indicated by ’||’ for
measuring time or frequency.
- Amplitude
and
time measurements, indicated by
’#’. The top text line displays the result of the
measurements (∆V or ∆T).
Step 5 Press the second bluesoft key until ’||’ is highlighted.
Step 6 The
TRACK
control moves both cursors at the same time. For
example, to measure the period time of the input signal, set the left
(reference) cursor to a rising edge of the signal.
Step 7 The ∆ control moves the right cursor only. Set this cursor the next rising
edge of the signal.
