Re: Repeating Triggering 6402c

Hi Hitesh,

it would be great if you could add this feature. Actually i am using the streaming-mode and check for a certain threshold. If this threshold is exceeded the program writes the data into a binary file. So this is a kind of soft- trigger which is highly computationally expensive.

Re: Repeating Triggering 6402c

Hi, with the updated driver dll files it works great. Do I have any chance to get absolute time information when I start a triggered measurement? For example I start a measurement but my Trigger occurs after 30 seconds. Is it possible to get this information (First Trigger at 30 sec, second Trigger ...

Re: Repeating Triggering 6402c

Hi,

attached you can see a measurement where I am sending a weighted sine pulse and the corresponding signal on the second channel. There is no problem with the trigger-settings.

Actually I am using the 64Bit dll files from the SDK but I don't know where to look up the version number.

Re: Repeating Triggering 6402c

I am using a Burst-Signal (Sine multiplied by a hamming-window) with arbitrary amplitude. When i use the PicoScope 6 software I can see the signal, and the repeated trigger does work. Am I trying to set up the same thing with the Matlab-Examples it does not. Regards ~edit~ I also can add the code, b...

Re: Repeating Triggering 6402c

Yes, I know, it always tells Turning off trigger when using connect(ps4000aDeviceObj); This seems to be the default option for the device. Default Channel Setup:- ----------------------- (...) Turning off trigger... But afterwards the trigger is set using the commands triggerGroupObj = get(ps4000aDe...

Re: Repeating Triggering 6402c

Hello, I've got a similar problem. I try to set a threshold on channel A to for example 1700 mV. Therefore I use the example PS4000A_ID_Block_Example.m where the commands set(triggerGroupObj, 'autoTriggerMs', 0); set(triggerGroupObj, 'delay', 0); % Channel : 0 (ps4000aEnuminfo.enPS4000AChannel.PS400...

Re: Connect PicoScope 5444B within function

Hi, actually the problem seems to be in picotech_ps5000a_generic.mdd. I added the following outputs (test1 to test3): disp('test1') if(isstruct(evalin('base', 'ps5000aEnuminfo')) && isstruct(evalin('base', 'ps5000aStructs'))) disp('test2') % Do nothing - structures have been loaded else disp('test3'...

Connect PicoScope 5444B within function

Hello, I am trying to connect the PicoScope 5444B within a function call. When I use the example-Scripts i.e. PS5000A_IC_Generic_Driver_Block.m everything is fine. Also sometimes connecting a device with for example function somefunction( void ) %SOMEFUNCTION Summary of this function goes here % Det...

Re: Use PicoScope 4225 as DAq

Finally i set

Code: Select all

...
set(streamingGroupObj, 'streamingInterval', 100e-9);
set(streamingGroupObj, 'autoStop', 0);
...
now it works!. But at the moment i am not 100 % sure if the measurements are completely continous or if there are lags between the taken measurements. Have you got any hint?

Use PicoScope 4225 as DAq

Hello, is it possible to use the PicoScope 4225 as DAq in combination with Matlab? I try to modify the PS400A_ID_Streaming_Example.m where i am limited to 2M Samples. My attemp is to Stream the data and copy it to my HDD using sprintf. The Problem is that I would have to clear the Buffer while measu...
