If I might inquire, what was the cause of the undefined header? I'm having a similar problem with an Agilent Signal Generator.

By using the correct commands as documented in the Programmers Reference Manual for your specific device. Just because your device says it supports SCPI, doesn't mean it uses the same commands as another similar device from a different manufacturer (and sometimes even from the same manufacturer).
SCPI only norms some basic parts of how to communicate with the instrument, but doesn't require the exact command tree, only that the commands should be structured in a tree. If the measurement system is called SENSE or MEASUREMENT for instance is quite arbitrary and depends on the manufacturer. Also these commands consist of a mandatory part which always needs to be written out and usually is written in uppercase and the rest is optional, but some devices only support the mandatory syntax or the full optional syntax, while other devices will accept any number of characters from the optional syntax between 0 and the maximum of the command.
