Source 1 and source 2, the same as source A and source B in the measurement
setting menu can be one of the channels (CH1-CH2). For the setting method, please
refer to the introduction in "Measurement Setting".
1. Delay 1→2: the time difference between the rising edges of source 1 and
source 2. Negative delay indicates that the selected rising edge of source 1
occurred after that of source 2.
2. Delay 1→2: the time difference between the falling edges of source 1 and
source 2. Negative delay indicates that the selected falling edge of source 1
occurred after that of source 2.
3. Phase 1→2: phase difference calculated according to "Delay 1→2" and
the period of source 1, expressed in degree. The calculation formula is as shown
in equation (6-1).
4. Phase 1→2: phase difference calculated according to "Delay 1→2" and
the period of source 1, expressed in degree. The calculation formula is as shown
in equation (6-1).
