Hi analogRF,
...try "*IDN?"
Good luck
like I said this instrument does not understand SCPI commands
same toughts
the keysight manual specify ID? and not IDN? for a id request, and it report only the model nothing more it seems,
It was asked in another thread here in the past
no SN sticker sound suspicious, these stickers don't remove themselves or fall off easily ?? is it an Fleabay purchase ?
