Is it possible to open the demo unit from C?

Hello,

I'm just wondering if we can open the demo unit from C.

I'm trying to test some code, but I don't have access to a full picoscope at the moment. Is the "demo" unit documented anywhere?

Re: Thread safety - PicoScope 6402 series

Does that mean that if I want to use multiple Picoscopes, I need to start forking off different processes???

Are there any plans to allow one process to communicate with multiple picoscopes?

Feature Request: Synchronous AWG

Hello, I would like to ask for a (new? )feature for the AWG in the scopes. Specifically, I am using the PS5244B (and 6403B). Currently, the AWG can trigger from an external source, but if a second trigger event occurs before the AWG record is played out it is ignored. It would be helpful to us, if a...

Re: (another) python library

Cython looks pretty interesting.

I'll probably use your project as a baseline the next time I want to interface some C code.

Re: Beta Release of Picoscope for Linux

I've had a few problems plugging in USB2 devices into USB3 ports. Can you check if that that is the problem? I feel like this is a general Linux bug that needs to be fixed.

Re: ps6000SetSigGenArbitrary

Good to know that this is the expected behavior and that it won't change in future versions of the SDK.

Thank you.

Re: ps5000aSetSigGenArbitrary output frequency calculation

Hi Karunen, Sorry, the A vs B was a typo on my behalf. I,m not at work today, but the version of the dll is the one that came with PS5000Asdk_r10_5_0_28.zip The issue is that bufferAddressWidth is not an integer. You cannot have log2(49152) = 15.6 bits. Typically, a bit width is an integer... This d...

ps5000aSetSigGenArbitrary output frequency calculation

Hello, I'm working with a PS5244A and I was having trouble getting the correct frequency output (repetition rate) from the arbitrary waveform generator. I am using the PS5000Asdk_r10_5_0_28 version of the sdk. The formula given in the programming guide outputFrequency = dacFrequency * deltaPhase ---...

Re: ps6000SetSigGenArbitrary

Hi Martyn, Hitesh, I've attached my sample code as well as plots showing the difference between the two methods of scaling. awg_scaling.png In the code I attached, I generate ramp from -2V to 2V measure it for a period 5 times its period. No trigger is set therefore it takes a bit of time before the...

Re: ps6000SetSigGenArbitrary

Hi Martyn,

About->Help only shows 6403 and does not specify 6403B. I guess the B is implied.

I'll go over my code again this weekend. Thank you.

Re: c++ PicoScope 6402B

The first parameter to openUnit should be a pointer TO the location where you want to save the handle. the handle is the identifier to the picoscope you are using for all your calls. therefore your code should look like something like this int16_t handle = 0; int r; r = ps6000OpenUnit(&handle, NULL)...

Re: ps6000SetSigGenArbitrary

Hi Hitesh, I am really at a loss as to which version of the PS6403. Looking back, it seems that I have a PS6403B because I am able to achieve up to 500,00,000 samples with the Picoscope 6 software by setting: divs = 20ms/div and 2GS for the samples This gives me a sampling interval of 400ps (I am as...
