Hi Jamie

What you can see is a feature called "quick dirty plot'. By defaults Sac does not show you all the points in your signal, but rather decimates them before plotting in order to save memory.
You can turn it off using 'QDF off' command ( https://ds.iris.edu/files/sac-manual/commands/qdp.html ).

I’ve had this problem in SAC when I read in high sampling rate (1000 Hz) data. When I plot it, it looks like it didn’t read in correctly (see attached figure). Is this a memory problem?
