USB6008 SINE WAVE GENERATION

[embedded systems engineer]

Hi all
iam generating sine wave with variable frequency for usb6008 which uses base DAQmx drivers.
iam sending my programme can any help me to generate the sine wave with vaiable frequency

Hi
all iam sending my programme , i couldnt able to generate the sinewave with variable freqency with USB6008
any one is having usb or experimented with that kindly give me a feed back.according to my knowledge DAQmx base drivers are very limited to development.

Thanks and regards

What behavior are you seeing when you run this code?

The USB-6008 and USB-6009 only support software-timed analog output (AO). This means that period between your AO updates will depend on the jitter of your operating system, inherent bus latency, etc. This is why it is very difficult to get a consistently fixed update period for software timed tasks. Hardware timed, in contrast, relies on the device having timing hardware which periodically update DACs (or sample ADCs, for AI).

Hi

I am also trying to generate sine wave of 60 Hz but with variable magnitude. I have  downloaded the example Cont Analog Out - SW Timed USB 6008 6009.vi and it is communication well with my daq card but I am unable to get the sine wave of 60 Hz. Is it possible to get a continuous sine waveform?. Also How do I know that the entire sine wave array has been passed to  usb daq card?. I dont have any other choice but to use this hardware. Pls help me.

Provide the link to this example.

You cannot pass an array to the device. You pass a single value at a time. The time is subject to jitter so please provide details on exactly you are seeing.
