Same on the alert! What a great deal on a solid entry level scope that I really can't justify right now... please stop, slickdeals!

Siglent is definitely a value-for-money option. I'd noticed a few years back where Keysight had started creating some nice offers in the education space for entry-level oscilloscopes, but they simply don't have to try as hard as their competitors. So many modern oscilloscopes from even basic brands (also see Rigol) are simply incredible devices well beyond the needs of an average hobbyist. Everyone sets their own needs/budget and honestly for me I've never beat the value and need for much beyond my old Analog Discovery 2 that I grabbed at a sub-$200 education discount way back when...

Good luck!
Jon
After watching a 15 minute tutorial on this device I still have no idea what it does.
Yep, I did this to mine. Keep in mind it's a 1GSa/s scope (500MSa/s if you use 3 or 4 channels) so 200mhz is pushing it a bit. You can also, um, liberate the other licensed functions pretty easily. Or you could when I bought it. Check eevblog forums to see if they fixed any of the hacks with newer firmware.

Since this will draw experts, could someone educate me a bit? I'm getting into tube amp repair/building (mostly repair/restoration currently), and see all the pro guys have an oscilloscope on their benches. I know one use case is to see the "signal" of the amp, in the context of tube biasing, to kinda know when the sine wave is "right". I don't have a background in electronics or circuits or anything, so I'm quite naive. What other use cases are there for something like this? What differentiates a $500-$1k scope whit a cheapo $20 USB type thing? What are different "channels" used for?
Its been a long time, but let me take a stab at this.

What it shows is what the electronics is doing at a particular location in the circuit. If you have multiple channels you can look at multiple areas at the same time which can make troubleshooting easier. A good example might be having an intermittment problem and you suspect its a capacitor, you could probe the capacitor and the problem area and see if the errant signal in the target area only happens when the capacitor is discharged etc. Or say that after a particular branch goes from low to high, you're supposed to see that reflected in a different place 100ms later... hard to do that if you don't have multiple channels. You could see that it changed, but you might not be able to see how long after it was triggered did it chance... or if its a pulse you might miss it completely if its not being monitored.

other than the # of channels is the sample/display rate, the voltages/current/time period it can handle.

This would be very tempting if I didn't have access to a couple scopes at work.

I was curious and this appears to be supported by sigrok:

Pretty sure this is not the first scope I've seen on slickdeals, but it seems to me that it's at least a decade or more since the last one I remember.

Nice deal. Last time I was seriously considering a scope I think it was a heathkit: it's been a few decades - amazing what a transformation digital has made of our world

EE here, this is more than enough for a beginner. It's enough for most engineers.

Old timer here. Just be careful of high voltage in any tube equipment. Lost 2 guys to lethal voltages from 'em over the years.

If you are on a budget and want something basic, try finding used Agilent's 54600 series scopes on eBay for 1/3 of the price. 100Mhz models 54645A, 54645D, 54622A, 54622D, 54624A (4 channel) are dirt cheap and they rarely break (in the worst case you just need to change out the NVRAM battery) even with age. This model series uses CRT screen and does not have fancy serial decoding or bode plot (these are all just software), but the interface is simple and intuitive so beginners are less likely to be confused by the clutter of advanced features showing up before the most common ones beginners would use.

Do you know what a multimeter does? A multimeter measures electricity, or electricity based signals. It gives you a number.

This does that, plus it gives a picture of how that signal changes over time, (volts - electrical pressure, amps - amount of electricity delivered).

Some of them can do a lot of other things, like compare multiple signals simultaneously, and do complex math operations on them.

It can do this on incredibly short timescales, down to millionths of a second.

This signal picture lets you know how your circuits are behaving, or whether your digital signal is being delivered or generated properly.

It's a groundbreaking tool for people who work with electricity or digital signals.

I have a Philips (from right around the time they got bought out by Fluke) 4 channel 200Mhz scope for 1/4th the price of this here, which is a cool hybrid analog/digital scope. While it works well, I definitely do miss all the fancy modern digital functions on it though, plus it's the size of a desktop PC. This thing is much smaller and you're probably more likely to use it if you do not have room for a dedicated workbench setup. Casual amateurs are probably well served by something like this.

I will say though, why have they been consistently expensive for an entry model over the years? I guess that is more a function of demand/supply than anything.
