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.
