Hello,
I have a NEFF 470 with an HPIB interface. I'm trying to retrofit with a USB/GPIB adapter. I have an Agilent 82357B and have gone through the steps to enable a side-by-side VISA installation, i.e. enabling the tulip dll in MAX and 488.2 in The Keysight Connection Expert software. The device shows up in MAX.
I have also located a driver listed as plug and play here: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9449659CE034080020E74861
All of the commands used in the library, however, are GPIB, and none seem to work -- even simple clear commands. I have read somewhere that these GPIB commands are incompatible with the Agilent GPIB/USB VISA and that I will need to use an NI adapter. This I can deal with, as long as I know this is the issue, i.e. before spending $600 on another adapter.
I have also tried using raw serial VISA read/write commands, which seem to work. I am not sure I can translate the entire library (or what I need of it) from GPIB commands to VISA, but if this would work I am also open to that.
Thanks,
Colin
