1 Connect the timebase output of the unit with the better timebase to the timebase
reference input of the other unit as shown in Figure 1-7.
For this test, make sure you always use the unit (Agilent 53131A/132A or
Agilent 8663A) that contains the better 10 MHz timebase as the output source as
shown in Figure 1-7.
