Re: PicoScope 3000Series Pretrigger in Streaming Mode

Hey, so i tried since yesterday to connect PicoScope 3206B and it says almost everytime: Warning: The library name case did not match the file name. The library will be named "ps3000a". Warning: The library class 'ps3000a' already exists. Use a classname alias. Error using instrument/delete (line 82...

Re: PicoScope 3000Series Pretrigger in Streaming Mode

hello, ok, i will give it a try to download the latest one. I already tried it in the past and try to connect and copy the right files to the right places, but in the past it doesn´t work. Maybe you can have a look at my system too: I have windows 7 64 bit, but i use 32 bit Matlab Version so i copy ...

Re: PicoScope 3000Series Pretrigger in Streaming Mode

I am using the sdk version : PS3000asdk_r10_5_0_29 and i think i define an application buffer with this function: invoke(ps3206B_obj, 'ps3000aSetDataBuffer', ... Channel_A, ... dataChA.pBufferNoneA, ... MaxBufferSizeChA, ... SegmentIndex, ... enuminfo.enPS3000ARatioMode.PS3000A_RATIO_MODE_NONE); If ...

Re: PicoScope 3000Series Pretrigger in Streaming Mode

Hello, thanks for your information. With the PicoScope 6 Software it works as expected, but i need this in my application by using the SDK with Matlab by using the streaming mode. I doublechecked the start and end indizes of this function: invoke(ps3206B_obj, 'AvailableData'); and i chose the maxbuf...

Re: PicoScope 3000Series Pretrigger in Streaming Mode

Hey,

in addition to the topic above, is there any known mistake regarding the start and end indices of the callback of the function:

invoke(app.ps3206B_obj, 'AvailableData'); ?

Re: PicoScope 3000Series Pretrigger in Streaming Mode

Hello, i am using the streaming mode. i developed a pre and posttrigger algorithm which works like the first in first out (FIFO) principle for the pretrigger data which i write into my pretrigger vector. It is pretty complicated to explain it by writing, but i want to try it. I had a look in each ce...

Re: Cannot connect driver to picoscope

hello, i have the following problem. My processing system worked with the sdk version 10_5_0_28 of PicoScope for Matlab. Then i updated the PicoScope 6 Software to the latest one, after that nothing works anymore. I can´t connect my PicoScope. The error is can´t find a specific library. So my questi...

Re: Generate a signal using the GEN Output Channel

Hello, unfortunately it still doesn´t work. I changed as you described the sweeps variable to = 0; This signal will be generated when i am calling the runstreaming function, even i have defined the triggersource to EXT IN. My EXT In signal is a 0-5 V TTL level, and the variable is where it should re...

Re: Generate a signal using the GEN Output Channel

Hi Karunen, sounds good, thank you. Maybe somebody else is also interested in generating a signal using GEN Output channel when a trigger occurs at the EXT In Channel. For some reason my GEN Channel sends the signal when i call the function, it is not waiting for the trigger, what did i wrong? Decla...

Re: Generate a signal using the GEN Output Channel

Hello, ok i understand. My system is a little bit difficult. I have sent "Hitesh" a drawing of my system. If you have contact to him, please get some information about my system. Do you know any kind of way how i can synchronize another system (it is a high speed camera) with PicoScope? My idea was ...

Re: Generate a signal using the GEN Output Channel

Hello, thanks for your help, it makes a few things clear. I meant, that every time PicoScope samples the buffer, let´s say a sampletime of PicoScope is 50 us then i want to to generate a signal (not specific a rectangular one) which has a rising edge, and the time difference between the rising edges...

Generate a signal using the GEN Output Channel

Hello all, i am using the Picoscope 3206B to synchronize this measurement system (PicoScope : 1st) with another measurement system (2nd, it is not a PicoScope, but it has a Sync Input which needs a specific signal). I connect PicoScope with the SDK of Matlab, i can capture data with channel A or/and...

Re: measuring current using PicoScope

Hello all,

I also have exactly the same problem measuring the voltage across a resistor. (R_shunt = 0.15 mOhm)

Also the idea to use 2 Channels of the PicoScope (3000 Series), it still doesn´t work.

Anybody an idea?

Hello all, i saved all waveforms of my data with the PicoScope Software. So now i have let´s say 20 .mat Files which has included my data that i processed. And now, i want to load these .mat Files into Matlab with a nice function which automatically plots the information of my 20 .mat files. I hope ...

Re: PicoScope 3000Series Pretrigger in Streaming Mode

Thank you Hitesh, okay i understand. But the function ps3000aRunStreaming expect the variable MaxPreTriggerSamples as an Input. So the example PS3000a_IC_Generic_Driver_2buffers_Streaming_SimpleTrig.m doesn´t work with an maxpretriggersample value higher than 0 ? (I think yes, because when the RunSt...
