• MSO54 different but synchronized time bases

    I'm using a MSO54, and I need to record (at each trigger) two signals which have very different time evolution (20ms and 100 ns).

    I therefore have the following problem : if I set the time base to see the first signal (20ms) I practically do not see the second (100ns), if on the other hand the time base is set on the second signal (100ns) I cannot obtain useful information on the first one.

    So my question is : is it possible to display and record (even just record would be fine with me) the two signals described in two separate windows with two different time bases but synchronized to the same zero time value?

    PS I know how to do this using two oscilloscopes but I'd like to be able to do it with one.
