Still looking for the perfect Valentine's Day gift? Have you considered a four-channel 200 MHz oscilloscope with virtual phosphor display?
@th (I'm actually pretty sure this costs more than the sum of all of the money I have ever earned in my life plus the remaining balance on my mortgage)
@gsuberland @th apparently the UXR series has a _base_ price of 195K and goes up basically hard vertical from there, so I have no doubt this scope is actually worth more than the _current_ value of my house, let alone the mortgaged value. And all the cars I've ever purchased.
@gsuberland @th at my workplace I have access to a Keysight Infinium Z-Series 63GHz and a LeCroy Waverunner 35GHz oscilloscope. They are *finicky* machines and you have to be careful not to hook up signals that can damage their input amplifiers and ADCs.
The Tektronix MSO-6B though… 
@datenwolf @th yeah and arguably I'd get more use out of 8x10GHz, especially with the MSO capabilities and power probe options. fully kitted out it still costs more than my house though.
@gsuberland @th How the hell do you even sample that fast? Do they have like 50 pipelined ADCs in a round robin?
I guess that's where some of the price comes from, if you're only selling like 10k of these ASICs and using your own custom fab then there's a lot of NRE and not a lot of amortization
A good logic analyzer is also up there in the "please impregnate me now" gift category.
@th 1st I thought that HDMI output on the front of an oscilloscope is very odd. Using HDMI connector for signal analyzer input is a little bit confusing.
@AliMirjamali one of the worst reuses I've seen is the OCP debug boards that route RS-232 levels to a USB Mini connector.
@th @AliMirjamali I can't remember what device it was on but I pulled something apart a while back that had an internal USB-A socket on the board with "NOT USB" written in massive letters on the silkscreen. the D+/D- were UART TX/RX, the GND pin was 5V, the VBUS pin was 12V, and the housing/shield was ground. cursed.
@th @AliMirjamali thinking back, I think Schneider Electric were involved, so cursed nonstandard interfaces are very much on brand.
@th @AliMirjamali @gsuberland suddenly very glad we didn't get hired there
@gsuberland @AliMirjamali one time I took apart a Compaq Portable III and found that the internal power supply used standard Molex connector for both 12V disks and the 200V gas plasma screen.
@gsuberland @AliMirjamali think of how much more transfer speed you would get if you plugged the disk into the wrong power connector!
@gsuberland @th @AliMirjamali How about "NOT ETHERNET -- THESE ARE RS485" which had +12V on three of the pins? Good times.

@phooky @gsuberland @th @AliMirjamali I think non-ethernet rj45 is quite common. Like having hdmi or similar stuff passed on it.
@gsuberland @th @AliMirjamali@mastodon.social At least they left you a note :p
@AliMirjamali @th It's not HDMI, just a similar shape. It's the input connector for the digital inputs from the optional logic analyser.
@th Very cool.
Vaguely related, I just read about a guy whose made a ring that runs Doom:

And then there's this God damned thing. "Very Rare!" (More Than 1135 Sold)
@th Got that exact one.
@th
Oooooo...❤️
@th I gifted myself one a few years ago. I don't use it nearly as often as I should, but when I do need it I am so glad it's there.
+2 for addition of googly eyes.
@th Got that last year, slept on the couch.
@th Not gonna lie this would 100% win me over
@th "Oh, honey! You got me an... oh... a Siglent."
"Is there something wrong? You don't like it?"
"No, no, it's fine, it's great. Thank you. I know you tried."
@th Now where to find a girlfriend that prefers those over chocolate and flowers ...
🤔
@th Remember that an oscilloscope is for life!
@th
I finally got to use mine for real to check the transmission line between my tape controller and tape drive (interfacing a 3.3V microcontroller to 5V MDTL chips)
@th I don’t have any use for that but its beautiful and i want it
@th Amazing what you can get for under $1K these days. My very first scope was a 2 channel used Tektronix 465B (150MHz) which I paid $800 for. Did a lot of stuff with that scope. Tek's latest innovation are probe connections that can be either an analog channel or 8 digital channels. So a 4 channel scope could have 32 digital channels. Even doing RF stuff I find the digital channels handy, especially for i2c components in the signal path.
@ChuckMcManis @th Yes understood .. but it's still "under 1K" ... is anything "reasonable" around $200 ? ( /me looks at his Tektronix 2205 found for 50 at Ebay years ago ) ... I still can't justify an expense more than 200 or so ..
@gilesgoat @th
Define "justify the expense" 😃 Does using your test equipment change your income? Either by allowing you to finish your use faster and potentially work more hours, or is associated with things that bring you income? Blog posts, substack posts, Etc. ? Even if you just use it for entertainment, what is your cost of entertainment without it? I really am curious.
@ChuckMcManis @th Ok said that "I could give some lessons to Uncle Scrooge" when it comes down to money 😊 ( about saving it ) it would be NOT for WORK it would be "for my own entertainment" and yeah, no, I can't see a thousand or such in that. If it would be for WORK I may not have a problem with that, it means I'd really need it. Part of me is scared that if I'd spend all that "for fun" then I may not have money when is REALLY needed for serious things.
@gilesgoat @th
I completely understand the scarcity trap. (see "Scarcity, why having too little means so much" for a discussion of that trap). And a $1K outlay for a hobby that generates no revenue is definitely not a good investment!
@th For Valentine's Day? Well, you certainly could make beautiful music with it...

@th For us it'd be the Digilent ADP3450 pleasssee, same idea :>
The ADP5xxx line *would* be nicer...
If it weren't for the Windows-only nature, and that the ADP3xxx have ethernet and the ADP5 only USB >~>
@th
I feel like half of the replies on this should be categorized as pornography
@th With four channels in and HDMI out?? What more could a girl ask for?
@th Can it play Tempest? If so, i'm in!
@th if someone bought me one of these I would have whatever surgery is necessary as a prerequisite to have their babies.
