-Duty:
-Duty Cycle, defined as -Width/Period.
Delay
A→B
:
The delay between the two channels at the rising edge.
Delay
A→B
:
The delay between the two channels at the falling edge.
Screen Duty:
Defines as (the width of the positive pulse)/(Entire period)
Phase
: Compare the rising edge of CH1 and CH2, calculate phase difference of
two channels.
Phase difference=(Delay between channels at the rising edge÷Period)×360
°
.
Note for the following delay measurements:
Source A and Source B can be set in the automatic measurement function menu.
FRR
: Time between Source A first rising edge and Source B first rising edge.
FRF
: Time between Source A first rising edge and Source B first falling edge.
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
