Hi Mathias

This time is the difference between the first sample in a block and the trigger event, found by linear interpolation. This is why you will get both positive and negative values.

It can be used to minimise trigger jitter. I don't think this is what you are after.

Hi Mathias

I have just re-tested this DLL and the auto trigger time was correct.

Is your application definitely running this DLL?

Are your captures still completing in 40 s?

Robin

Hi After looking in to this further, I found that I was incorrect in my previous post. Sorry. The value returned by ps2000_get_streaming_last_values is either 0 or 1. 1 indicates that the callback will be called and 0 indicates that it will not, either because one of the inputs is out of range or be...

Hi You need to call ps2000_get_streaming_last_values periodically, when you are ready to receive data from the device. The driver will then call in to your code, passing pointers to the location of the new data. The return value of ps2000_get_streaming_last_values is the number of samples that are a...

Hi

Here is the fix

Hi

The Delphi example was written for the older 2000 series scopes that don't support fast streaming.

I don't know much about Delphi, but shouldn't

sample_interval
max_samples
noOfSamplesPerAggregate
overview_buffer_size

be LongWord rather than LongInt?

It is in the software development kit (SDK), which can be downloaded via www.picotech.com/software.html

Here is a VI for the USB TC-08 saved for version 7.0.

Hope it helps

Hi Nick

Unfortunately, we don't have a LabVIEW example that uses ETS.

The function ps3000_get_times_and_values is available in the driver (ps3000.dll) and can be called from LabVIEW by using the Call Lbrary Function node.

Robin

Hi Patrick

You only need to call Run once and then you can call GetValues in your loop.

As you are using streaming mode, there will be no gaps in the data.

See collect_streaming() in pl1000con.c

Hi Mathias

This appears to be a bug that affects the 4226 and 4227 only.

I will post an updated driver here once it has been fixed.

Robin

Yes, thats a feature which i would need.

Hi Mathias

We have looked in to this and unfortunately it cannot be easily done. This is because device only tells the driver when all segments have been captured. Therefore, it is not possible to do this without changing the way the scope works.

Robin

This will be fixed in the next release.
