FFR : Time between Source A first falling edge and Source B first rising edge.
FFF : Time between Source A first falling edge and Source B first falling edge.
LRR : Time between Source A first rising edge and Source B last rising edge.
LRF : Time between Source A first rising edge and Source B last falling edge.
LFR : Time between Source A first falling edge and Source B last rising edge.
LFF : Time between Source A first falling edge and Source B last falling edge.
Other measurements
+PulseCount : The number of positive pulses that rise above the
mid reference crossing in the waveform.
-PulseCount
: The number of negative pulses that fall below the
mid reference crossing in the waveform.
RiseEdgeCnt
: The number of positive transitions from the low
reference value to the high reference value in the waveform.
FallEdgeCnt
: The number of negative transitions from the high
reference value to the low reference value in the waveform.
Area : The area of the whole waveform within the screen and the
unit is voltage-second. The area measured above the zero reference
(namely the vertical offset) is positive; the area measured below the zero
reference is negative. The area measured is the algebraic sum of the area
of the whole waveform within the screen.
Cycle Area : The area of the first period of waveform on the screen
and the unit is voltage-second. The area above the zero reference (namely
the vertical offset) is positive and the area below the zero reference is
negative. The area measured is the algebraic sum of the area of the whole
period waveform.
Note: When the waveform on the screen is less than a period, the period
area measured is 0.
Customize an Automatic Measurement
You can customize automatic measurements by using gating and statistics.
Gating

Press the Measure button, and the automatic measurement function menu
is displayed at the bottom of the screen;

Press the Set softkey at the bottom of the screen, the setting menu
appears on the right side of the screen;

Select the Gating menu. There are two menus: Screen and Cursor under
the range. Click the Screen and then click the Cursor , or press the right
