Re: How to install picoscope on Macbook

Hi kaito, Yes it is possible, but be aware that, for the current Mac version of PicoScope 6, not all of the functions available in the Windows version have been implemented in the Mac version. To install and run the Mac version you just need to download and install mono https://www.mono-project.com/...

Re: Low signal level in Spectrum option

Hi STMN,

The answer to your question depends upon what you are trying to achieve with your measurement. So, what exactly are you hoping to see from your measurement?

Regards,

Re: Start Trigger and Timer PicoScope Software

Hi Wilfred, What you are describing is a rising edge Trigger on channel A, which you can set by changing the Trigger Mode (the drop down window to the right of 'Trigger' at the bottom left of the screen) to 'Single' or 'Repeat' (depending upon whether you want to capture one waveform or many), then ...

Re: Low signal level in Spectrum option

Hi STMN, The answer to your question is because the time domain signal that you are looking at has frequency components spread out across the spectrum (which you can see in the Zoom overview). If you were to add up all of the frequency components, in the correct phase, then they would total to 170mV...

Re: Temperature measurement under strong electromagnetic fields

Hi avillegas, Unfortunately we have no off-the-shelf solution, for your specific application, but we do have a partial solutions that you could add required components to. So, in order to retain the accuracy by minimizing the effects of the high electromagnetic field you would need to use a method d...

Re: whatever SNR value you want without changing the signal

Hi Mathius, Just for clarification our specification of noise for the PicoScope 4444, where we quote <180uVrms, on the ±10mV range, this represents a noise ratio to the full scale range of 180*10^(-6)/7.07*10^(-3)= 0.02546, or 31.88dBc. So for a signal at say -1dBc that would be an SNR of 30.88dBc ,...

Re: RS485 (Differential) Hookup

Hi Neil, Modbus RTU can use RS485 (or now EIA485) or RS232, which use different physical connections, i.e. single ended and differential. So, the Serial Decoding provides connections for RS232, and lets you decide how to hook up the differential RS485. So your options are: 1/ Create a Math channel o...

Re: Noise Bandwidth/Res BW for Pico4262

Hi Michael, The Spectrum Mode provided in our PicoScope 6 software is performing a Fast Fourier Transform of the Digitized captured data, so it is not a Spectrum Analyzer, and therefore doesn't give you a Resolution BW control to vary the BW of the swept filter, so that you can control the frequency...

Re: whatever SNR value you want without changing the signal

Hi Math, First of all, the Forum post that you refer to was an answer to why our older version of the software had an error in it (which you will see if you scroll back up to the top of the post). The Forum user was referring to a very old video on Youtube that showed SNR measurement in very old sof...

Re: TC-08 giving + readings when they should be negative

Hi Thermalman,

It sounds as if there could indeed be a problem with the data logger.

Could you contact our Help Desk at support@picotech.com giving the same details (or referring to this post) so that we can help you further with this issue.

Gerry

Re: PicoScope 5444B

Hi Fabrizio, The Scope would be outside of it's operating temperature range, so your measurements would be inaccurate. But, more importantly, it would be outside of it's storage temperature range (for 60°C to 70°C) so you would risk damaging components (over time if not immediately). Regards, Gerry
