Cursor types
The cursor types are:
Time or Frequency cursors. These vertical cursors measure time or frequency, the
signal amplitude where the cursors cross the waveform, and the absolute
difference (delta) between the two cursors cross points (both time and amplitude
delta).
Time readouts are relative to the trigger point (which is 0 s). For example, cursors
to the left of the trigger are minus time values.
Amplitude cursors. These horizontal cursors measure vertical amplitude
parameters, typically voltage.
Screen cursors: A combination of both the vertical and horizontal cursors. Click
the Multipurpose knob to cycle through selecting the cursors.
NOTE. The vertical cursors in screen mode are not tied to where the cursor
crosses the waveform, and so do not show the amplitude value where they cross
the signal. Amplitude values are read from the horizontal cursors.
