Intermittent Timeout error during DAB

[Jerald]

Hi NI Community.

I have been experiencing intermittent timeout during the sending of binning results from the IC tester to the SE Probe PC through the hprintf() command.

NI Spy shows that the error is encountered on the SendDataBytes which took 16 sec. Input buffer seems find.

On the other hand, GPIB analyzer shows that in the second character of my data byte, NRFD^ was expected but was not sent. Instead, ATN^ was delivered which should not be the case as the data to be sent is not a GPIB standard command but a device specific string. ATN^ also took 16 sec. As observed, ATN^ is only called before and after the DAB. After the ATN^, UNL followed.

I am attaching the photo of the GPIB Analyzer to paint you the whole picture.

I am hoping for your help.

Which programming language are you using?

Why are do you need NI Spy?

Hi nyc.

We are using C++ programming language. I used NI Spy just to get some details along with the GPIB Analyzer logs.
