172 Keysight InfiniiVision 2000 X-Series Oscilloscopes User's Guide13 CursorsThe Y1 cursor is the short-dashed horizontal line and the Y2 cursor is thelong-dashed horizontal line.The Y cursors adjust vertically and typically indicate values relative to thewaveform's ground point, except math FFT where the values are relative to 0 dB.In XY horizontal mode, the Y cursors display channel 2 values (Volts or Amps).When active, the Y1 and Y2 cursor values for the selected waveform source aredisplayed in the softkey menu area.The difference between Y1 and Y2 (ΔY) is displayed in the Cursors box in theright-side information area.To make cursor measurements1 Connect a signal to the oscilloscope and obtain a stable display.2 Press the [Cursors] key.The Cursors box in the right-side information area appears, indicating thatcursors are "on". (Press the [Cursors] key again when you want to turn cursorsoff.)3 In the Cursors Menu, press Mode; then, select the desired mode:• Manual — ΔX, 1/ΔX, and ΔY values are displayed. ΔX is the differencebetween the X1 and X2 cursors and ΔY is the difference between the Y1 andY2 cursors.• Track Waveform — As you move a marker horizontally, the vertical amplitudeof the waveform is tracked and measured. The time and voltage positionsare shown for the markers. The vertical (Y) and horizontal (X) differencesbetween the markers are shown as ΔX and ΔY values.• Binary — Logic levels of displayed waveforms at the current X1 and X2 cursorpositions are displayed above the softkeys in binary. The display is colorcoded to match the color of the related channel's waveform.
