zoomed image dosen't update

Post by mdearman »

Hello,

I'm using the 5444B, I don't know if it's the same with all scopes. I want to capture a lot of I2C data and be able to zom in on it to see the detail. This is very acheivable by setting a long timebase and high sample rate then using the zoom function. The problem is on more recent versions of Picoscope the zoomed in image doesn't update to full resolution until you press stop which is quite annoying.

the upload functon on this page is also very annoying, I tried to upload pictures of what i meant but can't.
[edit by site admin] The error you reported should be fixed

Hi Mike,

Our Development Team have been notified about this before. Could you please send the corresponding psdata file to support@picotech.com and we can investigate further.

Hello Hitesh

I have seen the same effect on the 2204A and also on the demo instrument.

In the zoomed image, real time, the trace is broadened in the y direction until stop is pressed.
Monitoring in real time is not possible.
Once stop is pressed trace is then good.

Is this being addressed?

Hi Jim,

This issue has previously been reported to our Development Team with the response that this is expected behaviour.

The software is displaying aggregated data (a certain number of min/max pairs) with the complete data requested at the end of the buffer or when the data capture is stopped (resulting in the trace being redrawn).

The Development Team may look into a feature in order to fix zooming in streaming mode.

Hello Hitesh,
I face the same problem.
The zoom image shows a low resolution during streaming. After the stream is completed (single trigger mode) the resolution is decreased again instead of increasing it.
If the data is stored and opened again it is shown with a high resolution as expected. If the stream is stopped manually before it is completed the resolution is high too.
It seems that the behaviour is not as intendend.

regards,

BK

Could you please provide the corresponding psdata file so that I can run a test with your settings?

Thanks,
