Cursor Examples / 237
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.
Y Cursors Y cursors are horizontal dashed lines that adjust vertically and can be used to
measure Volts or Amps, dependent on the channel Probe Units setting, or they can
measure ratios (%). When math functions are used as a source, the measurement
units correspond to that math function.
