Re: Ion selective electrodes DrDaq

Hi Stephanos, Sorry for the late response. We can certainly help you with the data acquisition side of your measurement application. However, aside from my previous answer I have no more expertise on ion selective electrode setup with more than one electrode (our expertise is in using sensors with t...

Re: UART decode via SDK

Hi eiselekd, UPDATE 22/3/21 I have made some changes, and fleshed this answer out in a bit more detail, in response to a similar query from our Help Desk. The SDK is for developing your own applications, and we only provide examples of basic data acquisition (as the reasons for creating your own app...

Re: 2205A, noise level in Spectrum mode

Hi vit_s, You can't check the noise floor in Spectrum Mode because we apply an adjustment to the values displayed, in order to correct the peaks of signals for maximum accuracy. This correction changes the noise floor depending upon how many bins you select for the frequency plot (for more informati...

Re: Is it possible to measure the spectrum of extremely low frequencies (1 to 100Hz) with PicoScope?

Hi tomasz, I have given you a direct answer to your question, using a Secondary Spectrum view, in PART B below. I have also discussed how this would work in a Primary Spectrum view, and how to view the Time Gate in a more direct way when you have a Bin Width requirement (because, although this gives...

Re: how to measure noise spectral density in V/sqrt(Hz) vs frequency

Hi Shadi, We don't perform that in PicoScope 6. So, to convert the components of the Spectrum plot you would need to export the csv file, so that you can work on the data set (e.g. in a suitable tool such as Excel, Matlab or Python) and then do the following: First you need to detrend the spectrum (...

Re: 3206D does not show real time data

Hi Anik86p , Actually, ps3000aGetTimebase( ) is a check for your benefit, so that you can pass the values that you should be passing to ps3000aRunBlock( ). You use it to make sure that you have selected the correct values to use for Timebase (to get the sampling interval you need) and the correct va...

Re: Decoding CAN-FD signal

Hi GuidoW,

The stuffed bit counter should be using Gray code. While we are looking into this, do you have an example data file that I can pass on to our development team.

Re: 2406B Block Mode

Hi lamah,

Yes, it is possible and already done (for a much smaller block) in one of the Programming Languages/Environments that we support. You can find an example of this on our Github page here: https://github.com/picotech, which you can then download.

Re: Pico triggers multiple times in a short time

HI liuai987, Could you answer the following: 1/ Would this be In PicoScope 6, or would you be using the Software Development Kit? 2/ What PicoScope are you using? 3/ What sort of accuracy do you need (e.g. do you want to measure the height or rise-time with accuracy and if so what accuracy, or do yo...

Re: data collection/save rate

Hi weschang, The only way to conclusively answer your original question would be for you to paste the data files for a capture on both Scopes, with the Channel A of both Scopes set to the Input Range of ±20 mV, and nothing connected to the Channel A inputs apart from a 50Ω termination (e.g. in the f...

Re: Frequency Generator not Outputting Correct Amplitudes?

Hi aiyabunni, The offsets and amplification look OK, if you're using the x10 Probe switch i.e.: The second screenshot would be correct because the signal offset is 100mV, which gets divided down to 10mV. and the third one because a 1V amplitude (i.e. 1V peak) is being divided down by 10 to ≈100mV pe...

Re: 3206D does not show real time data

Hi Anik86p, The Bandwidth of the PicoScope 3206D is 200MHz, This means that pure sinewaves of 500MHz will be beyond what the PicoScope can capture according to its specifications, and therefore Pulses of 500MHz will be way beyond what the PicoScope is capable of capturing (see the information under ...

Re: data collection/save rate

Hi weschang, All I can say from what I can see on the left is that there appears to be no significant difference between the noise for the 2 Scopes. However, without knowing the absolute scaling that you're using, i.e. what proportion of the full-scale Input Range the amplitudes on the left represen...
