I'm trying to see a signal in zero span but it is all over the screen. How to I stabilize the display?
There are two basic ways to stabilize the display. It depends on the circumstances, as to which one is better. You can set the instrument to trigger a sweep based on an amplitude value, such as overshoot at the start of a pulse. If an external trigger signal is available, that is probably the easiest way to get a stable display. For the MS272xB, MS271xB and MT8222A, access the menu to set these things up using | Shift | Sweep | Trigger Type |. A possible third way is to adjust the sweep time to attempt to match the repetitation rate of the signal you are measuring. The sweep time can be adjusted in 1 microsecond steps.
