4． Falling Edge Count: The number of falling edges that fall from above the
threshold upper limit to below the threshold lower limit.
Note:
⚫ The above measurement items are only available for the analog channels.
⚫ The default values for threshold upper limit and threshold low limit are 90% and
10%, respectively. You can click Measure in the function navigation menu, then
click Setting to enter the sub-menu to set the parameters.
Delay and Phase
Source A
Source B
1． Delay A →B : indicates the time difference between the threshold middle
values of the rising edge of Source A and that of Source B. Negative delay
indicates that the rising edge of Source A occurred after that of Source B.
2． Delay A →B : indicates the time difference between the threshold middle
values of the falling edge of Source A and that of Source B. Negative delay
indicates that the falling edge of Source A occurred after that of Source B.
