Test Equipment / Re: Help me chose my pogo pin for THM Test Points on my PCB plz

No need for a high speed camera though - you have full control of the source signal, so you can create test signals and use a simple single-point optical sensor on a specific area of the screen.High speed camera and frame anlaysis is one way obviously.
If "screen update" means "pixels changed" (assuming a continuously changing input), then I think that's the only way
Unitrode had advanced replacements for the TL494, but after Texas Instruments bough them their selection guides were removed. I think they had a current mode control version of the TL494.
With mouse plugged into the scrope the scroll wheel is available for making numeric field adjustments.
That's interesting, must not have implemented that in the web interface
I have some doubts though, as I can see on the layout that it appears that the IR supply is just a 3V3 Zener diode dropping the 5V line.
How much current can a small SMD Zener usually handle?
>1A?
It is not an auxiliary coil that is used for deriving 5V for volt amp meter.
From the main transformer after full wave rectification, I have used it.
I want to derive variable power supply up to 30V and current limiting adjustable up to 5 amp.
