To Make Cursors Measurements
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 measurements on oscilloscope signals.
X Cursors
X cursors are vertical dashed lines that adjust horizontally and can be used to measure
time (when the source is FFT waveform, X cursors measure frequency)
X1 cursor is the left (default position) vertical dotted line; it can be moved to any place
of the screen.
X2 cursor is the right (default position) vertical dotted line; it can be moved to any place
of the screen.
Use the Universal Knob to set the X1 and X2 cursor values and the values are
displayed in the cursors box in the upper-left corner of the screen along with the
difference between X1 and X2 (
△
T) and 1/
△
T.
When set cursor type to X2-X1 , use Universal Knob will move the X1 and X2 cursors
together. The value under the menu option is the difference between the X1 and X2
cursors.
Y Cursors
Y cursors are horizontal dotted lines that adjust vertically and can be used to measure
voltage (V) or current (A). When the cursors source is the math function, the unit will
match the math function.
Y1 cursor is the top (default position) horizontal dotted line; it can be moved to any
vertical place of the screen.
Y2 cursor is the down (default position) horizontal dotted line; it can be moved to any
vertical place of the screen.
Use the
Universal Knob
to set the Y1 and Y2 cursor values and the values are
displayed in the cursors box in the top left corner of the screen along with the difference
between Y1 and Y2 (
△
Y).
When set cursor type to Y2-Y1 , use Universal Knob will move the Y1 and Y2 cursors
together. The value under the menu option is the difference between the Y1 and Y2
cursors.
