I'm connecting to an E4448A Spectrum Analyzer using the USB-GPIB connector. I am coding in Visual Studio 2005 C++. I can open a connection to the device successfully, but any time I send an SCPI command I see "CMD ERR, <expression>" (where <expression> is an element in the command string I send) at the bottom of the E4448A's display screen. There doesn't appear to be an error according to my code.
What is this error all about? I haven't found any documentation about this yet, although I'm still looking.
Thanks,

Thank you! I've been looking at this for the better part of a day now, trying to figure this out. The *RST command was working so I never thought that it was a configuration issue. I guess the *RST command is not a SCPI thing though?
Anyway, thank you!

and page 50 describes these. Of course, if you realized you were in compatibility mode to look for the manual, it wouldn't have been an issue!
