A C# example will be included in the next SDK release ( > 10.1.0.17 )

You can use the 32 bit dll's with a 64 bit O/S.

Put the dll's into the windows\sysWOW64 directory

You say you're using vb.net, so you'll need to use the functions in the ps3000wrap.dll wrapper dll. Take a look at the ps3000wrap.c to see their parameters. email support@picotech.com if you have further questions about it. The triggertimeoffset(bulk) function is used to calculate the time between t...

This error code would indicate an FPGA failure, which seems strange.

Could you try running the device using PicoScope 6.

If this works ok, could you check that your application is using the same PS4000.dll as the Picoscope application uses.

What type of trigger do you need?

Just a simple level trigger (using the ps3000aSetSimpleTrigger)

or a more advanced trigger, such as pulse width?


What conditions do you need to be met in order to trigger?

There is no API function to do this. You will just need write your code to add the offset, or calculate a percentage offset for the ADC count values you get back from the scope.

Try changing your parameters to something like this....


status = ps3000aGetTimebase2(unit.handle,timebase,4010,&timeint,128,&maxSamples,0);

So you will just need to add whatever offset voltage you want onto the mV value you calculate from the returned adc count, and the channel range.

A bug pas been fixed which may solve this problem.
A new PS5000.dll will be in the next SDK release. > R10.1.0.17

If using block mode, your application won't collect data until the device has triggered (If the trigger has been set) You will know what value you have set the trigger at, but won't know what voltage levels are being sampled. The application will be waiting for the callback to set the g_ready flag t...

Do you mean the voltage range? have a look in the programmers guide at the ps4000SetChannel function This is where you specify the voltage range you are using. http://www.picotech.com/document/pdf/ps4000pg-en-5.pdf Then to get the mv value back from the adc value returned from the scope, use the equ...

The Block mode callback is non-blocking, but the streaming mode callback is blocking, so the race condition won't occur. The callback is only called by the ps5000GetStreaminglatestValues call if there are values to collect, and will run to completion when called. The buffer size you set will depend ...

We have found a problem with the external trigger on the 4226 / 4227.

Please email support@picotech.com for a modified driver.

Could you send details of the ps4000.dll driver version you are using to

Our Linux drivers have not been updated for some time, but we are now working on Linux development for all of our new products.

There is no release date for these drivers at this time.
