Re: Sampling interval changed in streaming mode for long record length

Hello, I'm meeting exactly the same problem and I'm wondering if someone could help. I'm trying to do streaming for ~4.5 s with a high sampling rate (125 M/s) in my Matlab. After around 1.5 s, there are some distorted signals appearing in my input, such as missing part, changing interval, or even lo...

Re: Matlab Resolution is worse than Picolog 6 Software

Hi Gerry, Thanks so much for your explanation. I'm having one more question that may need your help with. One thing I found in my final data in channelBFinal (PS5000A_ID_Streaming_Example) is that the data is defined as int16 type (1 mV) which kind of too low resolution for me since my signal is usu...

Re: Matlab Resolution is worse than Picolog 6 Software

Hi Gerry, Thanks for your reply. I've attached my psdata file in the reply and it looks like there are some problems with my Matlab code and I've figured it somehow. However, I do have another two questions about Matlab streaming data collection and I'm wondering if you could help. 1) I've read the ...

Re: 4224A in Matlab

I met this problem too. I then install the windows SDK 7.1 in my win 10 following the instruction on https://social.msdn.microsoft.com/Forums/sqlserver/en-US/1de7c9b4-1feb-4c98-b426-f7f02cbafa99/windows-sdk-71-on-windows-10?forum=windowssdk. Now my streaming example can run. I'm not sure if this can...

Re: Matlab Resolution is worse than Picolog 6 Software

Hi Gerry, I'd like to follow this question since I have the similar confusion. I'm trying to measure the same signal with both matlab and my picoscope 5443D with the same settings (8 bits, 125 MS), and the PS graph is captured from my instant signal from channel B, not the average one. However, the ...

Waveform in PS and MatLab different

Hi, I'm trying to stream the waveform in MatLab. However, I found the result I capture in MatLab is different from what I get in PicoScope 6 (attached below) even if they're of the same setting (125 MS, 8bits). Basically, the waveform from MatLab is much noisier and I didn't get the echo signal whic...

Connecting PS 5443D to LabVIEW

Hi I'm trying to connect my PS 5443D to LabVIEW. I've downloaded and installed PicoSDK 10.7.19 (64-bit). The examples (both 5000 and 5000a since I'm not sure which one I should use) are achieved from GitHub. When I open the example file, it always warns me that cannot find some vi files (SubVI is mi...
