Re: Longtime streaming mode via USB problem

Hello, to digging deeper: I just read out directly the samples from Picoscop into the RAM. No drawing or anything, just read into the RAM (PC). In a post processing I draw some figures. All works fine to the point the USB-databuffer is full. (around 0,78s - as shown in the fig., see above). So i red...

Re: Longtime streaming mode via USB problem

Hallo Gerry, really thanks for your detail explination. After testing, I tought it runs that way. I'm a bit ... . Well, you "sell" this as fast streaming mode devices. But in fact, it's a oscilloscope and no device to store high speed data over a long time via USB. Anyway, I leared and have an oscil...

Longtime streaming mode via USB problem

Before I go deeper I would like to define my aim: Longtime data recording via USB, at least with a sample rate of 1024ns. To do that, i use the PicosCope 2206B with python 3.8 and the SDK. From the datasheet [1] I got the following facts: Max. Sampling rate: 500 MS/s (1Ch) | 250 MS/s (2Ch) Maximum s...

Re: ps2000aGetUnitInfo on python - sample?

After some search and couple of tries, I found a way to get the "ps2000aGetUnitInfo" running on python. To solve this, the sample code in Visual Basic [1] and details on the PicoScope 2000 Series (A API) guide [2] was helpful. For more Infos see [2] page 41 - ps2000aGetUnitInfo() - get information a...

max sample rate for 2206B is 16ns by ps2000aStreamingExample.py function

I use the PicoScope 2206B and with the PicoScope® 6 (6.14.23.5207) it's possible to grap data by 2ns (500MS/s). Pico2206B.jpg But, if I use the "ps2000aStreamingExample.py" all run fine down to a sample rate of 16ns. For that I changed two lines of code (timbase from US to NS) sampleUnits = ps.PS200...
