I'm pondering getting an oscilloscope for the laptop, i.e. one of those external cards that you plug into your computer. Any suggestions?

I think my new #oscilloscope has arrived 😁

sometimes i feel dull and really don’t know what to write, but music always gets me vibing. made some more stuff today.

Finally got back to getting the stop comparator card repaired in the 567 / 6R1A. It was a bad tunnel diode after all. You can see the curve has a super weak negative resistance region (the dip where the curve changes direction); it's supposed to be much more pronounced.

New video! I'm inspecting and testing an HH Electronic power amplifier from 1995.

I see my HDMI RX layout in a new light now that I have a solder-in 4 GHz active differential probe (Lecroy D420-A). The 0402 series caps are pretty small to solder onto (the other passives are the HDMI-to-GTP LR network). The ESD diode array footprint in front of the redriver-retimer is also tempting, but also so small…

Nano probe kits back in stock.

Great for debugging your project, on your desk, without resorting to the "big" Oscilloscope, power and leads.

Ideal for basic debugging of GPIO issues.

There’s an ethereal beauty of an analog sampling scope /almost/ working
#oscilloscope #analog #electronics #crt #retroTech

Voltage measurements starting to show signs of life after swapping out a few bum transistors in the 0% zone card. The 0% cursor isn’t working yet, so I don’t know where it’s measuring from, but I can get changing readings by moving the 100% cursor. The change roughly corresponds the peak to peak amplitude, which is promising.

It’s my first scope that runs Windows… 7… 😐
Probably better than Windows 11!

Well, that’s definitely bigger than it looked in the pictures! #oscilloscope #lecroy

Got time measurements working via manual cursors. Problem was in Stop Comparator card. Did a swap for now, but suspect Q54, will do component level troubleshooting next, but for now happy to get this closer to working.
0% zone still not working, which means no voltage measurements, and thus no automatic risetime measurements; that’s next on the list.

Next on the bench, the Tektronix 567 oscilloscope with possibly the first digital readout facility on any oscilloscope.
Swapping a bad tube in the regulator got all the rails up to spec. A few bad Nixie tubes in the readout unit were swapped, and now the real troubleshooting begins.

Look at this sexy-ass piece of engineering. Check out what happens when smart people harness downright magic.
It reminds me of the onion headline “Humanity Still Producing New Art As Though Megadeth’s ‘Rust In Peace’ Doesn’t Already Exist”.
Imagine seeing this and thinking “oh sure, but I’ll make something better”. GTFO, no you won’t. It’ll be faster and more accurate and cheaper and lighter and have a fucking touchscreen and USB, and a fucking subscription, and it’s going to have the soul of a republican, and every time you touch it, an MBA will get an erection.
GAH, this is just so damn pretty.
(And Rust in Peace is an epic, seminal album)

FG 100 DDS Function Generator

A function generator can be a great debugging tool for digital and analog circuits. There is a very cheap one floating around that's called the FG-100 DDS. What are its specs and is it any good?
