Cursor setups Cursor measurements
A vertical cursor readout includes and v aries directly with the Delay time, which varies directly with
the horiz
ontal position set for the time b ase. To see the amount of time to the first point, set horizontal
delay to 0.0 and set the horizontal reference point to 0%. Now the horizontal position readout shows the
time following the first point, and adding this value to the cursor readout yields the cursor position on
screen relative to first point. (You can find the horizontal readout both in the control window and in the
readout at the bottom of the screen.)
The following relationships hold:
Time from First Point = Horiz Position (when Horiz Delay and Ref Position are zero)
T1 readout = Time to First Point + Additional Time to Cursor
Cursor units depend on sources
A cursor that measures amplitude or time will read out in the units of its source as indicated in the table
below. Mixed sources require delta cursor readouts to use the units of the Cursor 1 source.
Cursors Standard units

Readout names
Horizontal volts, watts, IRE V1, V2, ΔV
Vertical seconds, bits, Hertz T1, T2, ΔT, ΔF
Waveform, Screen
volts, watts, seconds, bits, Hertz V1, V2, ΔV, T1, T2, ΔT

If the V1 and V2 units do not match, the ΔV readout defaults to the units used by the V1 readout.
Changing cursor positions
Change cursor positions by using the position controls in the Cursor Position window, dragging the cursor
into position using the touch screen or mouse, or by turning the front-panel multipurpose knobs.
NOTE. To make small changes with the multipurpose knobs, push the Fine button before turning the knobs.
When a Fine button is lighted, its multipurpose knob m akes smaller adjustments.
