LA
When using cursor to perform manual measurement on the waveform of the LA
channel, the display mode is fixed at "X" and cannot be modified (only the X cursors
are displayed). When different horizontal measurement units are selected, the cursor
measurement results are different. The measurement results (displayed at the
upper-left side of the screen) include the following measurement items.

CurA: the X value at cursor A (X cursor).
D15D0: display the logic level values at cursor A (X cursor) in hexadecimal and
binary forms (D15 to D0 from left to right). For digital channels that are turned
off, "X" will be displayed, denoting that the level is unknown.
CurB: the X value at cursor B (X cursor).
D15D0: display the logic level values at cursor B (X cursor) in hexadecimal and
binary form (D15 to D0 from left to right). For digital channels that are turned off,
△X: the horizontal difference between cursor A and B (X cursors).
"X" will be displayed, denoting that the level is unknown.
Press Cursor  Mode, turn the multi-function knob
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 LA channel waveforms and displays the measurement results at the
upper-left side of the screen. When the manual measurement parameters are
modified, the measurement result will change accordingly.
