I have to ask Dima @dimpase, my fellow behind-the-Iron-Curtain denizen: mate, do you recognise these older Tektronix oscilloscopes?
Some of the 1950s Tektronix scopes in this Tek museum in Oregon look remarkably like the then-new Soviet scopes supplied to my engineering school in Burma, back in the 1980s.
Found a low mileage #nikon D810 for a good price and decided to take the plunge.
Here’s a #tektronix type O operational amplifier plug-in in a Type 132 power supply, which lets one operate a plug-in outside of its host #oscilloscope.
2 flash setup, one with a soft box, the other a bounce. 105mm #macro lens.

Imagine spending your weekend trying to play #Doom on an #oscilloscope with #Lissajous #figures 
—because obviously, that's the pinnacle of technological advancement. 
Well, at least the forum threads are more entertaining than actually trying to make it work.

Is it possible to play doom on an oscilloscope using only lissajous figures?
Here it is in action numerically solving the Lorenz Attractor differential equations.
The #Rigol DHO814 (100 MHz, 12-bit, 4-channel) digital #oscilloscope is hard to beat for the home #electronics laboratory market.

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

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…
