Cursor Measurement
Cursor measurement can measure the X axis values (usually Time) and Y axis values
(usually Voltage) of the selected waveform. Before making cursor measurement,
connect the signal to the oscilloscope and acquire stable display. All the “Auto
Measurement” parameters can be measured through cursor measurement.
Press Cursor  Mode at the front panel and use to select the desired cursor
mode (the default is “OFF”) and then press down the knob. The modes available are
“Manual”, “Track” and “Auto”. When the
Time Base Mode is set to XY, you can
select the XY cursor measurement mode.
Manual Mode
In this mode, a pair of cursors will appear. You can adjust the cursors manually to
measure the X (or Y), X increment (or Y increment) between cursors and the reciprocal of
X increment on the waveform of the selected source (CH1-CH4, LA or MATH). When the
measurement source is set to LA, the logic level value of the digital channel currently
turned on will be displayed in hexadecimal forms (high level is 1 and low level is 0).
Press Cursor  Mode  “Manual” to turn the manual cursor function on. To easily
read data, the display form of measurement results on the upper left corner of the
screen changes with the measurement source and unit selected.
When the measurement source is set to CH1-CH4 or MATH:
 When the measurement source is set to FFT (press MATH  Math 
Operator  “FFT” and press Display to select “ON”; press Cursor  Source
 “MATH”), if the horizontal unit selects “s”, the measurement form is as shown
in figure (a); if other units are selected, the measurement forms are as shown in
figure (b).
 When the measurement source is non-FFT, if the horizontal unit selects “s”, the
measurement form is as shown in figure (c); if the horizontal unit selects “Hz”,
the measurement form is as shown in figure (d); if other units are selected, the
measurement forms are as shown in figure (e).
