Hi to all,
I uploaded here a code of DTMF dial tone generator but when i connected through NI DAQ card 6008 it shows a error code, i have attached you a .png file and also i uploaded actual vi, go through that and reply me ASAP.

Very easy, the Analog-out of a USB-6008 can only be updated in software-timing mode, max. about 150 Hz/s, i.e. you can set only 1 new value (not a waveform), and only with about 150 Hz software-timing. Or in other words, you can only use DAQmx-Write-> Analog-out -> 1 sample.

Thanks for the reply but i've changed whatever you've said but still it's showing the same error, is that any other thing i need to take care of?

I think you are still using timing(sample clock).vi , as jens said the card you are using wont support this function. timing

Thanks for your reply bharath, is there anyway to generate a DTMF signal using usb 6008 for higher sampling rate?

hi
The card specification says max 10kS/s. you can generate upto that if you are using single channel. Try using 1chanNsamp

Wrong!! That's the maximum sampling rate (aggregate) for analog input. For analog output see.page 2 of the device spec document
For analog output one can only use X chan-1 sample.
@paulrobinson: No, there no chance at all to generete a DTMF signal with that card.

Hi jg,
Thanks for the reply and can i generate using specified frequency for the given DAQ card? because i removed the timing function and directly added into the samping info column of the signal generator, and runned it but every time it shows error, can you suggest me to do the right method or i have to use different card because i also have usb 6211 with me, is that possible to do with that card?
Thanks again,
Regards,
Dinesh
