Cursors
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.
The Y1 cursor is the short- dashed horizontal line and the Y2 cursor is the
long- dashed horizontal line.
The Y cursors adjust vertically and typically indicate values relative to the
waveform'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 are displayed in the softkey menu area.
The difference between Y1 and Y2 ( Y) is displayed in the Cursors box in
the right- side information area.

To make cursor measurements

1 Connect a signal to the oscilloscope and obtain a stable display.
2 Press the [Cursors] key.
3 In the Cursors Menu, press Mode; then, select the desired mode:
204
The Cursors box in the right- side information area appears, indicating
that cursors are "on". (Press the [Cursors] key again when you want to
turn cursors off.)
Manual — X, 1/ X, and Y values are displayed. X is the difference
•
between the X1 and X2 cursors and Y is the difference between the
Y1 and Y2 cursors.
