“X-Y”, the horizontal measurement unit is “s” and the vertical measurement unit is set
to "Source Unit".
You can use cursor to perform manual measurement on the waveform of CH1 to CH4
or MATH channel following the steps below.
1. Turn on the manual measurement function
Press Cursor Mode, turn the multi-function knob to select “Manual” and
press the knob. You can also press Cursor or Mode continuously to switch to
“Manual”. At this point, the oscilloscope measures the values at the cursors of
the specified source channel waveform and displays the measurement results at
the upper-left side of the screen. When the cursor measurement parameters are
modified, the measurement result will change accordingly.
2. Specify the measurement source
Press Source and turn the multi-function knob to select CH1 to CH4 or
MATH. You can also press Source continuously to switch the current source. If
“None” is selected, no cursor and measurement result will be displayed.
Note: Only channels currently turned on can be selected.
3. Specify the display mode
Press DisplayMode and turn the multi-function knob to select the desired
cursor display mode. You can also press DisplayMode continuously to switch
the current cursor display mode.
X: only display the X cursors (a pair of vertical solid/dotted lines).
― You can select to measure the time (s), frequency (Hz), phase (°) or
ratio (%) using the X cursors by setting the “
horizontal
measurement unit” (Time Unit).
― The measurement results include A->X, B->X, △X and 1/△X (only
displayed when Time Unit is set to “s” or “Hz”).
Y: only display the Y cursors (a pair of horizontal solid/dotted lines).
― You can select to measure the amplitude (the unit is tha same as that
