Hi all, im trying to comunicate with some instruments: Waveform Generetor HP 33120A and Oscilloscope TEKTRONIX TDS 694C through a National Instrument GPIB-USB HS. I have an evaluation labVIEW version and I'm waiting for the valid version. I have NI VISA 16.0 and NI 488.2 16.0 installed. My problem is that when I scan from instruments from NI MAX there appears an error:
" VISA: (Hex 0xBFFF0015) Timeout expired before operation completed".
Opening Visa test panel, in the section INPUT/OUTPUT there is no error writing a command and MAX recognize the GPIB primary address of the instruments. The problem should be while reading from instruments. It's like if it doesn't answer to the *IDN?\n command. I read about the file NiVisa tulip.dll and I enabled it. But there is always the same problem. Can you help me? Thank you and best regards.
