Hello,
I got a latest 3203D scope.
It has a problem "PICO NOT FOUND" on some system with Labview.
With PicoScope 6 software it work everywhere.
Say I got it work on two old Windows 7 system, but it do not work on never Windows 7 and Windows 10 systems.
I had upgraded latest drivers from your site, and put newest ps3000a.dll in appropriate Labview folder.
The old Pico 3204B scope I have work perfectly on all systems with new driver.
I suppose it some compatibility issues of new driver/ps3000a.dll.
Does you have encountered such a problems?
Hi,
All updates are installed on all the systems.
I use USB 2.0 ports. But on systems there 3203D work with SDK USB 3.0 controller exists on chipset . On systems there its do not work - no USB 3.0 on computer. The problem seems to be pure software because PicoScope 6 handle all the cases smoothly.
Of cause I do not open more than one instance of Pico drivers at time: no PicoScope with Labview at same time.
Do you have some old driver/SDK version that support 3203D? I would like to try it...
I would like to thanks to Pico support team for resolving my problem.
I post the solution for the other interested users:
If you wrote code for old PicoScope3000 device and buy a new one, you will discover that it will not work under USB2.0 port.
The solution is to include another function call:
It should come immediately after call off
int32_t _ps3000aOpenUnit@8(int16_t *handle, int8_t serial);
As a powerSource input parameter send a ps3000aOpenUnit function returned value.
Ignore non-zero return of ps3000aChangePowerSource.
Example for LabVIEW exists at:
Another issue to pay attention on: TimeBase parameter calculations are changed in new PicoScope3000. It affects analog input sample rate and phase shift calculations for AWG.
