I am using this Labview example software from https://github.com/picotech/picosdk-ni-labview-examples/tree/master/ps5000a/32-bit-examples. It runs ok and captures the waveforms like I need, but I want the x-axis in the graph to be accurate.
For example, in my screenshot the waveform has 3 periods over about 140 samples. In real life this is about 300ns. My project depends on measuring the time between the peaks, as shown by the peak detector. Any ideas?

Hi,
I have updated the example on Github to return time Interval on graph (x-axis), for this example-

Hi,
Thanks for your help. I am unable to start it. I downloaded the new library and the updated program from the links you posted. This is the error message I receive:
PicoErrorHandler2.vi library error message
When I doubleclick on the error message, it goes to this module on PicoErrorHandler2.vi block diagram.

I am able to locate the 'missing' node in the dll file. I don't understand why LabView lists it as 'Library not found'?

I think it is solved now. I repaired the 'PicoSDK_32_10.6.13.97' file that can be found on the product downloads page, which seemed to correct the library issues I was having. The screenshot of the signal corresponds to 100 samples. The x axis displays a total signal time of about 300ns.
