Cursor Examples 163
Cursors are horizontal and vertical markers that indicate X- axis values
and Y- axis values on a selected waveform source. You can use cursors to
make custom voltage, time, phase, or ratio measurements on oscilloscope
signals.
Cursor information is displayed in the right- side information area.
Cursors are not always limited to the visible display. If you set a cursor,
then pan and zoom the waveform until the cursor is off screen, its value
will not be changed. It will still be there when you return to its original
location.
X Cursors
X cursors are vertical dashed lines that adjust horizontally and can be
used to measure time (s), frequency (1/s), phase (°), and ratio (%).
The X1 cursor is the short- dashed vertical line, and the X2 cursor is the
long- dashed vertical line.
When used with the FFT math function as a source, the X cursors
indicate frequency.
In XY horizontal mode, the X cursors display channel 1 values (Volts or
Amps).
The X1 and X2 cursor values for the selected waveform source are
displayed in the softkey menu area.
The difference between X1 and X2 (
Δ
X) and 1/
Δ
X are displayed in the
Cursors box in the right- side information area.
