This may be of some help: https://www.eevblog.com/forum/testgear/picoscope-2000/msg1905005/#msg1905005 Python script to gather "infinite stats" (by default PS6 is limited by stats over 1000 measurements). This can be easily modified to output CSV since "machine readable" output is already parsed fro...

If this is of any help I sometimes managed to get little better results by nesting filters with same params eg this for 20MHz: BandPass(BandPass(A,19999990,20000010),19999990,20000010)

Following may be of some use if want to have arbitrary and fixed ref level for measurements w/o configuration like Pulse Width, Duty etc: In this example ref level is set to 0V, so can be steered around on real signal with DC offset (or additional math). Clip signal -100mV...+100mV: ((abs(A-0.1)-(A-...

For signals with approx. same frequency, example on channels B, C - calculates unsigned difference: B=1MHz, C=1.01MHz graph(delta(B,C)) = duty((((atan(1/tan(pi*(B/10000)))/pi)+(B/10000))*-((atan(1/tan(pi*(C/10000)))/pi)+(C/10000))))*(1/200)*(1/freq(C)) B=1MHz, C=1MHz, 15° phase delta(B,C) = ((((atan...

If you need to visualize on scope to compare with other signals etc you can decode with MCU (Arduino for example) and feed the numerical result as bit pattern into MSO digitals, which can be shown as analog graph of changing value. https://www.picotech.com/support/topic27831.html https://playground....

One can use multiple viewports to view same signal and gain extra set of rulers with each one.

Bump, issue is still in the air:

User cannot automate decoded data export because macro recorder does not see SD window. Also it might be problem that SD/Export does not offer auto naming of export file.

It may not be looking at the zero crossing. Apparently not. That's because it does not calculate phase difference ;) From wiki: power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load to the apparent power in the circuit, and is a dimensionless nu...

Hi, magenta trace - derivative(A) lime trace - (A[0.000000002]-A)/0.000000002 Latter is 1 sample point time advanced (2ns) due to nature of function. Cant integrate none of them. Only way to make ref wfm and integrate then. Result perhaps sheds some light why it is not working in real time. purple t...

When it comes to simulation would you say that an Arduino that has two sinewave outputs so that you could delay one of them to get the 44 deg shift? You mean Due? Due is good fast board can do a lot with it. With Uno can hook up two MCP4725s or even just PWM and and make it a sine using physical lo...

Hello and thanks for the great help. In the earlier simulations you did how were you able to shift chB red trace around 60 degrees or so? It is actually 44°, scaling may give wrong impression. But simulation is exactly that, simulation - all smoke and mirrors ;) Actual data is coming in from signal...

This may be an issue due to the way data is collected and processed on the low memory 2205, which doesn't support memory segments on the device as our other scope models do, instead handling this within the driver and application. Hi, initially I discovered the "walking math" phenomenon on 2408B so...

Thanks very much for explaining this. In your code you use T. Where is the T in the equation below? To calculate an integral you have to have a T don't you. Technically integral is calculated using this in Pico software, quite different to WolframAlpha examples: https://en.wikipedia.org/wiki/Numeri...

How do you get 14.88 from integral(A*B)

Ok, enough messing around
115 * 0.18 * cos(0.768) = 14.89

MAX(P(A*B)) integrate (115*sin(x)) * (0.18*sin(x)) * (2/pi); 0 to pi https://www.wolframalpha.com/input/?i=integrate+(115*sin(x))+*+(0.18*sin(x))+*+(2%2Fpi);+0+to+pi P(A*B) integrate (115*sin(x)) * (0.18*sin(x-44pi/180)) * (2/pi); 0 to pi https://www.wolframalpha.com/input/?i=integrate+(115*sin(x))+...
