Ibwrt problem with HP11713A attenuator controller

[haes de baerx]

I'm programming HP11713A attenuator controller. First I writed one *.cpp file and I managed to controll the device the way that I wanted.

Now I'm writing the final version and using c++ classes (controller.cpp, controller.h and main.cpp). I really don't know what is wrong, because ibdev and ibclr functions are successfull, but when I'm trying to write to the attenuator controller with ibwrt I get these error messages:

iberr: 0 (EDVR)
ibctrl: -536215496

Hi,

That is strange since usually EDVR errors are generated at initialization.

Just a few questions:
What GPIB interface are you using?
What driver version (NI-488.2) and OS are you using?
Do you have a code snipet that reproduces the error?.

Hi!

I managed to solve my problem. It was a stupid copy-paste error that was hidden in a long code. Took a while to debug...

Thanks anyway DiegoF!
