What exactely does the display show you ?

Re: Fft
Q. What is the FFT (Fast Fourier Transform) math function of an oscilloscope useful for?
A. There are a variety of uses that can benefit from viewing the frequency spectrum of a signal. Using the FFT math function on a time domain signal provides the user with frequency domain information and can provide the user a different view of the signal quality, resulting in improved measurement productivity when troubleshooting a device-under-test. Examples include:
Analyze harmonics in power lines
Measure harmonic content and distortion in systems
Characterize noise in DC power supplies
Test impulse response of filters and systems
Analyze vibration

Is this oscilloscope sufficient to analyze all points on a laptop motherboard? PWM of IC and mosfets for example, or detect communication between super IO for example?

This is a new item at Electronic GoldMine that has arrived within the last few weeks
Here is the link for them I know for sure that it works because ( I tried it on mine soldering station ) I bought two of them and I just bought two more of them so I have some extra replacement ones in my parts bin
Stahl Tools DDDS Replacement Iron for DSDS Stahl Solder Station

One note it will not work for the ZD-917 or similar model number that does not have the sleep function that are the same iron but the plug only...11-24-2024, 01:25 AM -
Hello everyone, I'm troubleshooting an MSI Delta 15 (MS-15CK1) motherboard, and I need help identifying the function of the two coils marked in the attached image. The laptop powers on and responds to the keyboard, but the screen does not turn on-neither the LCD nor the backlight. I've checked the main power rails, and all other coils seem to have the expected voltages:
• 0.91V for the GPU
• 1.7V for VRAM
• 3.3V and 5V rails 1.8V for the BIOS
• 0.9V for the CPU and iGPU 1.2V for the RAM
However, these two coils are not showing any voltage.... -
I have recently acquired a Dynamco D7100 analogue oscilloscope without a user manual. As this is the first time I have owned or used an oscilloscope I would like to try and find an instruction book. The manufacturers no longer hold any information and a Google search only found one site but when I downloaded a 'service manual' all I got was gobbledegook. Any help would be gratefully appreciated or even pointers to a generic manual where I could learn more. -
All,
Some of you have helped me in the past and I am very appreciative of all the help! (I have fixed TVs/Stereos/ and other small appliances with your efforts...Thanks so much!!!
Today I went to a local HAM Radio Festival. It was one of the smaller ones in our area. My stepfather is the HAM operator. I tinker in electronics but am a Software Programmer (27 years now).
I was looking for a few odds and ends for some electronics work I have to do for the household/farm. Typically these type of shows have the grab bags or a electronics vendor...
