Re: How can I fix this error code -1300..

That explains the error you got from the LV driver. The first thing it
does is send the ID? string to get the type of instrument. There's a
few more things you can try. Check or replace the GPIB cable. Try a
different instrument and see if you can communicate with it. If that
works then you know your cable and GPIB board are OK. Check the
address setting on the instrument. Try different commands to program
the instrument. Contact Agilent  or check the manual to see if there's
any dip switches/front panel buttons/menu options on the instrument
that need to be set.
