Re: 64 bit PicoScope API

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

Put the dll's into the windows\sysWOW64 directory

Re: Trigger troubles

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...

Re: ps4227 error codes

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.

C:\Program Files\Pico Technology\PicoScope6

Re: Trigger troubles

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?

Re: Picoscope 4227 and Voltage position

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.

Re: Ps3204A and ps3000aGetTimebase(2)

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


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

Re: Picoscope 4227 and Voltage position

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.

Re: time trigger

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...

Re: Picoscope 4227 and Voltage position

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...

Re: ps5000 callback thread racecondition

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 ...

Re: PicoScope 3206 and Linux

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