12 CursorsY CursorsY cursors are horizontal dashed lines that adjust vertically and normallyindicate Volts or Amps, dependent on the channel Probe Units setting. Whenmath functions are used as a source, the measurement units correspond tothat math function.The Y1 cursor (short- dashed horizontal line) and Y2 cursor (long- dashedhorizontal line) adjust vertically and indicate values relative to thewaveform's ground point, except math FFT where the values are relativeto 0 dB.In XY horizontal mode, the Y cursors display channel 2 values (Volts orAmps).When active, the Y1 and Y2 cursor values for the selected waveformsource are displayed in the softkey menu area.The difference between Y1 and Y2 (Y) is displayed in the Cursors box inthe right- 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, indicatingthat cursors are "on". (Press the [Cursors] key again when you want toturn cursors off.)3 In the Cursors Menu, press Mode; then, select the desired mode:• Manual — X, 1/X, and Y values are displayed. X is the differencebetween the X1 and X2 cursors and Y is the difference between theY1 and Y2 cursors.• Track Waveform — As you move a marker horizontally, the verticalamplitude of the waveform is tracked and measured. The time andvoltage positions are shown for the markers. The vertical (Y) andhorizontal (X) differences between the markers are shown as X andY values.156 Agilent InfiniiVision 2000 X-Series Oscilloscopes User's Guide
