Re: ps6000GetValuesBulk makes (throws) an access violation

Thanks Martyn.

The example Code is OK, because it is working fine for PicoScope 4227. The buffer allocation is correct.

I understand the advantage using Rapid Mode. For now, we will have to use the Block mode.

Re: ps6000GetValuesBulk makes (throws) an access violation

Immediate Block woks OK
Rapid Block with 1 capture => Not Ok (access violation)

Does Rapid Block mode work for you? Do you use the same DLL version as I do?

Re: ps6000GetValuesBulk makes (throws) an access violation

We are trying one segment in rapid mode. When using a block mode it works as expected.

Re: ps6000GetValuesBulk makes (throws) an access violation

I am wondering about this.

Based on PicoScope 6404B specification it should be possible to acquire 256MS per BNC. We are trying to acquire only 3MS, and it doesn't work :/

The same works fine with PS 4227...

Re: ps6000GetValuesBulk makes (throws) an access violation

However, Rapid Mode works for all 4 BNC Channels in case when the number of acquired samplings is set to 10000 (for example)

Re: ps6000GetValuesBulk makes (throws) an access violation

Okay. Does it mean Rapid Mode on PS6000 works only for one channel?
With PS 4000 you can use all channels.

Thanks

Re: The last sample point in the scope buffer has an invalid

Hi Martyn, below you can find the last five indexes with the corresponding ADC values. The last two values (a and b buffer) are invalid. This occurs sporadically. As stated before I am using the rapid trigger mode with only one capture and with external trigger. Both channels have 2V range (because ...

no, I am using my own software.
May I send you ADC counts?

Re: Trigger question

yes I know this. I need to this dynamically. That means the default auto trigger timeout is infinite in my case. In my scenario I have to generate an external trigger pulse when the pre-trigger buffer is still not full. That means my requirement is that the scope "remembers" the trigger request, and...

Trigger question

Hi,

Is it possible to tell the scope to trigger immediately after the pretrigger buffer become full?

Thanks in advance.

Kind regards,

How to Trigger on specific edge duration?

Hi, I have PicoScope 4424. We have a scenario where we have to trigger on falling edge. The first voltage threshold is at 12V and second is at 2V. The time duration between these two thresholds varies from 2µs to 10µs. The trigger should fire in case of 2µs edge duration only. Kind regards, Bane

Hi Robin,

trigger property is not changed.

The picoStatus.h is not included in ps4000 SDK.
I found the file in ps5000 SDK. Can I use this one?
I am asking because ps4000 and ps5000 SDKs are different.

If you like I can send you the code with the trigger configuration?!

Regards
Bane
