When in the automatic functions of Pulse Width and Rise/Fall Time, the signal being
measured on the UCT is on a single channel and the Common mode is automatically
enabled. Channel 1 and 2 inputs are internally connected to allow the UCT to minimize
propagation delay and mismatch. When in Common mode it is not possible to make
measurements of INPUT2.
