Congratulations!

I am very happy today! We passed an extended TUV ISO-13485 inspection for the "Design and manufacturing of medical equipment". There is an incredible amount of detailed paperwork to keep track of

I've not heard that name for those before. We have one situation in this house where one of those actually came in handy. There's an outlet in the laundry room with the washer and a refrigerator

Hmm, I didn''t know that was in there. I just looked, and that program happens to be installed on this machine. I'll have to play with that a bit... -- Member of the toughest, meanest,

Normally the ground lead of a scope probe is connected to the ground of the scope and this ground is connected to the safety ground of the AC power input.? One can remove this safety ground with

I doubt if your VCO has any DC response since it appears to be a high Q device.? Start with a model.? The more detailed the better you should try to show 2nd order effects or higher.? The VCO only

This is way complicated interface but appears to be intrinsically safe and "idiot proof." I consider all of us to be idiots at the worst possible moment so please don't take it as an

A friend suggested this program as it has normal oscilloscope display, phase (XY) Lissajous, FFT, and a signal generator. "Visual_Aanalyzer_Freeware" at https://www.zeitnitz.eu/scope_en The FFT

I'll be the first to agree the AC Mains is seldom [?never?] a pure sine wave. I suspect the mains have higher distortion today then when we were in college because of all the switch mode power

Hello,I have built a PI controller I have its time domain step responce and AC responce. PI controller is supposed to help with the DC part of the error signal of a PLL system. I cant undertnad how,Is

I agree, a sinewave is not interesting - but sometimes the mains waveform is not a sinewave, and then you really really need a 'scope to see it.. Back in college, I remember that the lab's AC mains

i have the st-link v2 st cube programer and a 64k bluepill board,does anyone know if i can flash a bootloader to enable programing over its usb port using arduino ide?.

OK an oscilloscope is probably the wrong tool for this job. Consider a battery powered laptop operating on battery power with a resistive attenuator. Laptop internal audio line inputs run anywhere

Hi, Mostly to learn how to do it safely. What I’ve learned in my past, it’s good to know stuff before I need to know it. I tell kids I mentor that we (maybe) need 1/10 of everything we

What exactly are you trying to see? There has been a lot of interesting discussions on how to "safely" connect an oscilloscope to the AC Mains. So, what is your goal? What are you trying to see on

I'm not well versed on the subject, But I wonder if it would help to drive one channel of your scope through a well filtered say 6V transformer, then the other channel connected to the ac line with a

PID control is not required for PLL operation.? Your loop filter should be a simple low pass chosen such that the frequency sum terms are removed and frequency difference terms are preserved. This is

You clearly know what you are doing and have an extremely good reason for monitoring the AC Mains. You need to see near instantaneous changes in the input and output. Very few people have that
