Period
Source A and source B can be any channel from CH1 to CH4.
1. Delay A→B : the time difference between the rising edges of source A and
source B. Negative delay indicates that the selected rising edge of source A
occurred after the selected edge of source B.
2. Delay A→B : the time difference between the falling edges of source A and
source B. Negative delay indicates that the selected edge of source A occurred
after the selected edge of source B.
3. Phase A→B : phase difference calculated according to “Delay A→B ” and
the period of source A, expressed in degree.
4. Phase A→B : phase difference calculated according to “Delay A→B ” and
the period of source A, expressed in degree.
