Re: PicoSDK for Mac with arm64 architecture

Hi Picotech Team,
I second this! Mac's new architecture is out for some time now. I was very negatively surprised that I cannot use the SDK.

Re: Deadtime measurement

Hi Gerry, yes this is still an open question. My student is still working on it. I think she wants to finalize within a week, though. I think you have my mail address as we are writing about the PicoPyGui App of mine. So you could also send a not so polished version via mail, if this accelerates thi...

Re: Scope 2208A as counting module

Hi PhotonCoder, don't know if your question is still active. If yes: I am doing a similar application in python. I count pulses in order to get the rate. However, our rate is smaller. So I think in your situation 2 options are available: 1) rapid block mode with short recorded pulses, taking as many...

Re: Alternating use of two PicoScopes 4224 in rapid block mode

Hi Student, I am also using a picoscope for PMT readout. Maybe we could speak more directly than here? I have an application which does an "almost" continuous readout using rapid block mode. My application is measuring the rate of pulses as well as producing a PE spectrum live. However, it does make...

Deadtime measurement

Dear all, this is not a beginner's question but rather a setup / calibration of the device question. Please move, if this is wrong for this sub-forum. We are characterising a picoscope 3406D MSO and try to measure the gap time (deadtime + setup time) between rapid block mode triggers by using regula...

Re: Device often not found - Segmentation fault

Hi,

I finally upgraded my OS to 10.12 (Sierra) and switched to work with Python3.
This solved the issue of not finding the device and getting a segmentation fault instead.

Thanks for all the help.

Best,

Anna

Re: Device often not found - Segmentation fault

Hi, I answered this to support, but it might be interesting for others too: The issue doesn’t occur on Windows and I rarely tested on Linux. Thus, it seems to be a Mac (or python implementation on Mac) problem, since I’m using the exact same program on all computers. The problem is reduced when I un...

Re: Relative time between triggers Rapid Block Mode

Hi, I find things still a bit unclear. In rapid block mode the software does one data record, then it needs some time to recover (dead time) and then it listens again and waits for the next trigger. I understand that the function doesn't include the dead time. But what is with the time the device is...

Re: Device often not found - Segmentation fault

Hi,

it gets better (still not perfect) on Mac when I turn off power for the picoscope, deconnect the USB and execute
$ pkill -9 python
Then I connect everything again and wait for 5 seconds.

Best,

Anna

Switch between channels or use them in parallel

Hi, I'm programming a python (pyQT) application for a 6404B. The python code accesses the SDK libraries, based on https://github.com/colinoflynn/pico-python. I am currently taking data in the rapid block mode using channel A over ~ hours. I connected a temperature correlated signal to channel B. I w...

Re: Device often not found - Segmentation fault

Hi,

here are the Screenshots from the Segm. Fault I get from my terminal application and from your Application.

BTW: I tested the software and my terminal application on Linux Debian and Windows 7.
I get the same problems there (a few starts without recognizing the Picoscope).

Best,

Anna

Re: Device often not found - Segmentation fault

Hi,

I changed to Mono 4.0.4. I still have to open the GUI or my own application several times until they find the device. In addition I still get segmentation faults. However, both is reduced in number.

I will post the screenshot as soon as I do the next measurement.

Best regards,

Anna

Device often not found - Segmentation fault

Hi, I started to work with a PicoScope 6404B and to write my own DAQ for a photomultiplier. I use the python API from here https://github.com/colinoflynn/pico-python. I noticed for both, the standard Mac GUI and the API, that the picoscope is found at start only every ~10th trial. In addition, if I ...
