Advantest R376x trace input via GPIB (LabView 7.1)

[Bandic]

I'm developing an application that can be used to save the registers to computers harddisk and the other way.

I can read all scale,display etc parameters and the trace itself(memory or fmemory1/2). These values are saved to disk.

(At this point I usually recall some other register.)
I also can write all parameters succesfully to analyzer. When I write the trace to analyzer it doesn't give any error messages or anything. I just can't see the trace anywhere in any channel.

I use the instrument driver's trace input/output vi's to input/output the trace. For reading/writing the other parameters I use simple vi's by me.

I would be very thankful if someone could help me with this problem.

Pasi,

What do you mean by "write the trace to analyzer"? Did you actually acquire anything with the analyzer?

There are some application examples come with the instrument driver, try run those examples and see if they work first.

You also said "For reading/writing the other parameters I use simple vi's by me." Do you mean that you wrote your own VIs?

Problem solved, the trace goes to analyzer, but the display must be refreshed. This is done by changing the refline value to something and then to the original value.

--I transfer display and trace data analyzer to pc and pc to analyzer.
I had to wrote my own vi's because instrument driver didn't provide all the vi's I need.
