hello, trying to capture the longest possible time span at 10GS/s, single channel, single sweep, with 2Gpoints. in the acquisition menu tried setting the sampling & memory to various combination of auto or manual but am not able to capture the 2Gpoint measurement. although at 80Gs/s, 2Gpoint is available, dont understand the logic but this time span is too short for the measurement. beside the acquisition pull-down, is there another menu that is preventing the capture of 2Gpoints at 10GS/s? also there is a discrepancy between the main screen displayed number of points (memory depth) and the acquisition menu, one could set the memory in the acquisition menu to 1Gpoint while the main display show 500Mpoints, although what is saved is 1Gpoint. the scope is also controlled via python (pyvisa) in case the fix is only available via remote commands. the attached is the screen capture from help infiniium.

There are several things that can affect the ability to get full memory depth. If you look in the Help, search for 'Things That Affect Maximum Memory Depth'.
The two that might be affecting you right now are:
- Full depth (2G) is only available if only half of the Oscilloscope is used (Either Channels 1,2 or 3,4)
- Full depth is only available if you are in 'Single' Mode. In run mode, to improve throughput, the memory is ping-pong'ed.
