Manual Mode
In this mode, you can adjust the cursors manually to measure the values at the
cursors of the specified source channel waveform. The measurement results will be
displayed at the upper-left side of the screen. When the measurement parameters
are changed, the measurement results will change accordingly.
Note:
The channels available include CH1 to CH4, MATH and LA. Only channels
currently turned on can be selected.
When the source channel is LA, the display mode will switch to X mode
automatically and cannot be modified.
CH1-CH4 or MATH
When using cursor to perform manual measurement on the waveform of CH1 to CH4
or MATH channel, if the settings of the cursor display mode, measurement source,
horizontal measurement unit and vertical measurement unit are different, the results
of cursor measurement are different. The measurement results (displayed at the
upper-left side of the screen) can include more or all of the following measurement
items.
A->X: the X value at cursor A (X cursor).
B->X: the X value at cursor B (X cursor).
A->Y: the Y value at cursor A (Y cursor).
B->Y: the Y value at cursor B (Y cursor).
△X: the horizontal difference between cursors A and B (X cursors).
1/△X: the reciprocal of the horizontal difference between cursors A and B (X
cursors).
△Y: the vertical difference between cursors A and B (Y cursors).
The figure below shows the measurement results when the cursor display mode is
“X-Y”, the horizontal measurement unit is “s” and the vertical measurement unit is set
to "Source Unit".
