△X and 1/△X. Wherein, A->X, B->X and △X denotes frequency and
position as reference). The measurement results include A->X, B->X,
1/△X denotes time.
results include A->X, B->X and △X (expressed in degree).
°: measure the phase values at the X cursors. The measurement
The oscilloscope allows you to set the phase reference positions
according to your need. After adjusting the X cursors to the desired
positions (refer to step 6 "Ajust the X/Y cursor positions"), press
SetCursor and the current cursor A and cursor B positions are defined
to "0°" and "360°" phase positions respectively; at the same time, two
unmovable vertical cursor lines (with relatively lower brightness) are
displayed on the screen as the phase reference positions ("0°" and
"360°" phase positions are marked by a solid line and dotted line
respectively). Before you setting them manually, the oscilloscope will
use the default phase reference positions.

%: measure the ratio values at X cursors. The measurement results
The oscilloscope allows you to set the ratio reference positions
according to your need. After adjusting the X cursors to the desired
positions (refer to step 6 "Ajust the X/Y cursor positions"), press
SetCursor and the current cursor A and cursor B positions are defined
to "0%" and "100%" ratio positions respectively; at the same time, two
unmovable vertical cursor lines (with relatively lower brightness) are
displayed on the screen as the ratio reference positions ("0%" and
"100%" ratio positions are marked by a solid line and dotted line
respectively). Before you setting them manually, the oscilloscope will
use the default ratio reference positions.
Source Unit: measure the amplitude values at the Y cursors (take the
channel ground as reference). The measurement results include A->Y,
