Hello, we send command to initialize a HP54603B oscilloscope and GPIB communication with it hang up, I must power on/power off to restore GPIB communication. The file attached list the commands send to the oscilloscope (init from event 6204).
You can refer to the section on "GPIB Error Codes and Common Solutions" (option 3) from ni.com > Support > Top Hardware Solutions > Instrument Control > GPIB, to debug the error. Did you try using "VISA Interactive Control" C:\VXIpnp\WinNT\NIvisa\NIvisaic.exe and directly communicating with the instrument to isolate the issue?
