5 Making Measurements
178
Y cursors are horizontal dashed lines that adjust vertically
and normally indicate Volts or Amps, dependent on the
channel Probe Units setting. When math functions are used
as a source, the measurement units correspond to that
math function.
X1 and X2 — The X1 cursor (short-dashed vertical line) and
•
X2 cursor (long-dashed-vertical line) adjust horizontally
and indicate time relative to the trigger point for all
sources except math FFT (frequency is indicated). In XY
horizontal mode, the X cursors display channel 1 values
(Volts or Amps). The cursor values for the selected
waveform source are displayed within the X1 and X2
softkeys.
The difference between X1 and X2 ( X) and 1/ X are
displayed on the dedicated line above the softkeys or in
the display area when some menus are selected.
Turn the Entry knob to adjust the X1 or X2 cursor when
its softkey is selected.
Y1 and Y2 — The Y1 cursor (short-dashed horizontal line)
•
and Y2 cursor (long-dashed horizontal line) adjust
vertically and 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). The cursor
values for the selected waveform source are displayed
within the Y1 and Y2 softkeys.
The difference between Y1 and Y2 ( Y) is displayed on the
dedicated line above the softkeys or in the display area
when some menus are selected.
Turn the Entry knob to adjust the Y1 or Y2 cursor when its
softkey is selected.
X1 X2 — Press this softkey to adjust the X1 and X2 cursors
•
together by turning the Entry knob. The X value will
remain the same since the cursors adjust together.
You can adjust the X cursors together to check for pulse
width variations in a pulse train.
