Voltage measurement with PICOSCOPE 6404D

Postby sankhachandra » Wed Nov 29, 2017 7:19 am

Hello,
We have Picoscope 6404D. It is connected to the computer by USB3.0. My question is How can I measure voltage from labview interface? I have already downloaded the labview SDK examples. I can see the signal from that vi.But the voltage information I am not getting. Please help me out of this problem. Thanks in Advance.

Hi Sankhachandra,

The values are returned as ADC counts from the driver which is what the example displays.

In the shared folder of the GitHub repository there is a PicoScope.llb file containing a sub-vi that converts ADC counts into a voltage value.

You will need to place this in the block diagram for each channel ensuring that the enumeration representing the voltage range for each channel is connected to the block for correct calculation.

Hope this helps,
