Where is the Internal 80MhZ reference for the 6608 counter/timer card defined in the CVI DAQ library?

I can only find The following defines:
ND_INTERNAL_20_MHZ and ND_INTERNAL_100KHZ.
But I can't find a ND_INTERNAL_80_MHZ

It could be that the enumeration just isn't up to date. You should post this question to the counter/timer forum here so the timing experts can respond to your question.

Hello

Try checking out the ND_INTERNAL_MAX_TIMEBASE. This will let you use the maximum time base your device supports

This is mentioned in the function help for GPCTR_Change_Parameter in the NI-DAQ function reference manual. You should have that installed on your machine if you have NI-DAQ installed.

Hope this helps

Hi,
Couldn't find ND_INTERNAL_MAX_TIMEBASE under the GPCTR_Change_Parameter but it did come up under the GPCTR_Watch.Which gives me the impression that I can only query for the value but not use it as an argument to the GPCTR_Change_Parameter function.....but I will give it a try.
Thanks,
Carl

Hello;

To use the 80MHz with PCI-6602, you need to call GPCTR_Change_parameter and ND_INTERNAL_MAX_TIMEASE for paramID=Source. You will find this documentation under GPCTR_Change_Parameter function in NIDAQ Function Reference Manual.

Felipe,Thanks,
When I drilled down from the paramID=Source I was able to get to the ND_INTERNAL_MAX_TIMEBASE description being used for the paramValue. I would have never been able to get to that point without help.....
