Re: TA189 30A difference in the rise/fall time

I had done the same measurements to compare different types of current clamps and a 0.1 ohm shunt. Below the rise times of various clamps v.s. shunt (TA300 can be compared to the TA189 I think) current clamp rise-times.png Below the fall times of various clamps. current clamp fall-times.png The ring...

Re: trouble connecting to picoscope with Matlab

You can not have the picoscope software running while you are using the SDK.

Re: PS 4824A Missing Data in Streaming Mode

My python is not good enough to debug your code. But for that speeds you certenly need to use C or C++ and probably threads to post proces the data. So 1 thread reading the data from the scope to a giant ring buffer. High priority. And 1 or more threads evaluating the data in the rung buffer. (lower...

Re: Trigger when transmissions start or stop

You can trigger on rising and faling edge of a signal. 2022-06-24_07-32-18.png Direction on Rising or faling. Be aware that if the faling edge is shortly after the end of the capture of the start, the faling edge will not fire because the scope is busy transferring data to the PC and not reading the...

If all ground references are the same then this is no problem.

Re: AWG performing very poorly on new 2204A unit

Try a cable directly from the AWG output to the scope input.

Now I see a grey AWG output probe to a crock clip disappearing and then a BNC connector coming back.

Re: AWG performing very poorly on new 2204A unit

Can you also post a photo of your setup, to show you don't have a load on the generator.

ex a 50 ohm or 75 ohm attenuator.

Re: Is there a possibility to read binary saved scope files?

It is possible, depending your hacking and programming skills it will take 1 week or forever. But you can use automation to convert psdata to csv files as far as I know. You can write a simple C# / C++ / Python program to read the CSV files and produce the data you need. That is far simpler than rev...

Re: Can I decode I2C with Picoscope 7 on OSx

you can try yourself on this .psdata file.

There is also a I2S signal but the I2C is decoded.
If the decoder works on OSx then it will work for your scope.
You can download the software from this site and test with the attached data.

Re: Pico 3204D MSO - Python Data Logger

I have this scope and use it from C++, even made a 24V converter for the digital inputs.
So you can safely monitor 16 24V signals with uS precision times.

Re: Pico 3204D MSO - Python Data Logger

Is there a streaming mode sample ?

for a 20 second sample you need to use streaming mode that can be infinitely long.
Look at.
