@OLderDan:
I also have such a waveform (attachment).
The signal generator shows 5MHz and 10MHz is measured because the AWF is already 2Hz.
The amplitude/PkPk is correct.
Have you set the impedance to "High-Z" or 50Ω (second page of the signal gen)?
OLderDan:
Does this mean if I make a sine wave with 2 complete cycles I can only trigger on the start and no point elsewhere? Please accept my apologies if I am asking some basic level questions and revealing my stupidity.
I have searched Google for information, which was how I discovered using the 50ohm settings reduces the PtP voltage to 3.3v down from 7volts when in the hi-z mode. I am trying to create a square wave 0-5v and another 0-3v for triggering uprocessors, and struggle to get appropriate offset on the built in generator while the built in test pulse has the correct levels, but is only 1khz!

No.

Leave it at High-Z if you are not using a 50Ω load and even then... leave it at High-Z.  ;)

This works for 3.3V (attachment), but not for 5V. The positive voltage of the AWG is probably limited to 3.5V, as the specified maximum amplitude is 7Vpp.
Perhaps a logic level converter could help?
OLderDan:
Could someone confirm for me the largest size SD card that can be read. After my original 8gig got sick of the terrible (read non existent) unmounting choices, I chucked in my 32gig brand name USB stick I noticed I could no longer save any file type either internal or external. I could read files fine, but any attempt to save resulted with a hang on the progress bar anywhere from 20% to 50% depending on the file type.
I was freaking out until I found another 8gig card and I now I could write all file types to both SD card and internal.

Should be FAT32 formatted, NTFS or others won't work.
