The default 77 ns delay corresponds to 50 feet of 0.66 velocity factor coax... probably the most typical installation. You can set the cable delay to whatever you want.
The Kalman filter option is only implemented in the Thunderbolt-E firmware. It is grayed out on the regular tbolt (but is still selectable just in case it is/was ever supported by a different firmware release).
The eXpand ('x') command sets the plot scale factors for 1 hr/division. The View ('v') command is similar, but lets you set the length of time to view in the plot area. It may do a little tweaking of the specified value to get the plot divisons aligned to nice round time intervals.
The daY ('y') command does the same thing as 'x', but also sets up the plot area for 24 major divisions for a full day display.
