To Make Cursor Measurement 
 
Cursors are the horizontal and vertical marks that can be used to measure the X axis 
values and Y axis values on a selected waveform. All the 29 waveform parameters 
(please refer to Table 6-5) supported by one-key measurement can be measured 
through cursor measurement. The cursor measurement function provides the 
following two kinds of cursors. 
 
Note: Please connect the signal to the oscilloscope and obtain stable display before 
using cursor measurement.  
 
 
 
 
 
  X Cursor 
X cursor is a vertical solid/dotted line used to perform horizontal adjustment. It 
can be used to measure time (s), frequency (Hz), phase (°) and ratio (%). 
―  Cursor A is a vertical solid line and cursor B is a vertical dotted line.  
―  In the X-Y cursor mode, the X cursor is used to measure the waveform 
amplitude of CH1 or CH3. 
  Y Cursor 
Y cursor is a horizontal solid/dotted line used to perform vertical adjustment. It 
can be used to measure amplitude (the unit is the same as that of the source 
channel amplitude) and ratio (%). 
―  Cursor A is a horizontal solid line and cursor B is a horizontal dotted line. 
―  In the X-Y cursor mode, the Y cursor is used to measure the waveform 
amplitude of CH2 or CH4. 
 
Press Cursor (in the function menu at the front panel)  Mode, turn the 
multi-function knob   to select the desired cursor mode (the default is “OFF”) and
