I have been using the example LabView VI to take readings from my parallel ADC-11/10. When reading from a stable voltage source at about 10 times per second, each reading varies by as much as 30mV. Appearing as noise when the values are plotted.
However looking at the reading from the same channel in PicoScope the voltage 'wobbles' no more than 1mV. I am sure the actual voltage is not changing at all as it is simply taken from a battery.
I also tried calling the adc11_get_value_and_time function from LabView. This showed similar noise and also appeared to be returning the 'value' parameter scaled to 4096 rather than 1024?
The 30mV noise is too much for my application, so any help with why it shows up in LabView but not PicoScope would be greatly appreciated. Thanks.
