Hello All,
So what i am trying to do is get one of our HP 3457A DMM's to communication via the GPIB bus. This is an older piece of gear that is equipped with HPIB. I have had luck communicating with other HPIB instruments but can't seem to get any queries to execute properly. The device will beep when i execute commands but is not excepting them so I must be missing something. To begin i am simply trying to get a simple response from an identification query. This device is not SCIPI compliant, according to the manual i should execute a command something like OUTPUT 722;"ID?" . According to the manual the "7" refers to the HP-IB select code which default is 7 i am assuming that hasn't changed and the "22" represents the address on the bus which i have confirmed is in fact 22. Also speicficed in the manual is the device recognizes a <CR> , <LF>, or ; as the EOI character. I am using NI-488.2 communicator to test this. Attached is a screen shot of what i am trying to do and what I am seeing.
Any help is greatly appreciated.
Thanks,
Josh
