Hi All,
I am using an ADC-11 with labview 8.5. I have been using the usbadc11_single.vi to read from the ADC-11 but I am getting a lot more data than I need and this could be a problem as I only need to measure a low freq signal over very long periods. I would like to be able to change the sampling frequency, ideally from the front panel. Any help or example VIs will be very appreciated

Eskinder,
If you wish to change the sample frequency you will have to call each function separately rather than using the Labview single function. I have attached a example to get you started. The function that you will want to concern your self with is the UsbAdc11SetInterval function. This routine specifies the time interval per sample and the number of samples to collect. Refer to your user manual located in the C:\Program Files\Pico Technology\Pico Full folder to go over the requirements of these functions and their use.
