gpib explorer

Hi,

When I try to use NI GPIB explorer to communicate with my oscilloscope 5464a, an error "QUERY UNTERMINATED" is reported.

I tried another oscilloscope 54621D, this error message is still reported.

What's wrong?

Anyone can help? Thanks.
 

gpib communication

Hi,

There are several possible reasons.

1) Have u install the GPIB card driver properly ?
2) Is the GPIB cable plug in properly ?
3) I am not sure how NI GPIB explorer works, but just can try change the GPIB address of the equipment to factory default.
4) If u are familiar with Labview or Agilent Vee even Ansi C, u can try write simple codes to communicate with the equipments, that would be able to isolate any hardware connection fault.

Hope it helps.
