SV: vrf GPIB spoll

Question asked by VRFuser on Jul 20, 2008
Hi Les

 

Take a look at the example in C:Program FilesAgilentVEE Pro 8.5examplesInstrumentIOInstrManagerIntegratedAg87xx-VNA. This should give you an idea about how to create the required looping around the SPOLL object.

 

I’m using VEE Pro 8.5, but the example is present in earlier versions too…

 

 

Best regards,

 

Kenneth Rasmussen

 >  But still I would like to know were the loop is? Is it in the GPIB driver or is VEE just looping within the spoll object?

 

I think the loop is inside the VEE code itself, because I don't remember any "C" command that says "stay here until spoll gets the right answer." -- In "C" you do the spoll, check the masked value - repeat until done.  I'm sure VEE does that too - it just hides the details from you.  What you need to do is say "no thanks" and do: repeat until - spoll - mask - compare as desired - done - else - wait 10. (or something like that.)
