EE here, this is more than enough for a beginner. It's enough for most engineers.
10-04-2022 at 10:33 AM
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.
10-04-2022 at 10:33 AM
For a beginner I would get a $70 old school surplus oscilloscope honestly.
10-04-2022 at 10:33 AM
Yes, it has far more features than a hobbyist will likely ever need, but it is at a great price point for what it provides.

If you're going to buy new, I would not recommend buying a lower quality/cheaper scope. If you're looking for something extremely basic, you can find some junk oscilloscopes on eBay or Alibaba.

https://www.ebay.com/sch/i.html?_nkw=oscilloscope&

Just don't expect them to be accurate or durable.
10-04-2022 at 10:33 AM
Yes. That's exactly the intended use case. This is great for hobby level work. Most people won't outgrow this. If you do, you're likely upgrading to a scope that is 5x the price.

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.

Ggggggggggg...Google!

An oscilloscope is an instrument that graphically displays electrical signals and shows how those signals change over time. Engineers use oscilloscopes to measure electrical phenomena and quickly test, verify, and debug their circuit designs. The primary function of an oscilloscope is to measure voltage waves.

Unless I've forgotten all my instrumentation knowledge, I don't think this can. The bandwidth is 100MHz (200 with some hacking) so you'd be short quite a bit.

This same model was frontpage back in 2020 for $17 more, with 11 pages of "what does this thing do?"

Analyzing digital or analog electronic hardware. Think Arduino-type stuff, or repairing electronic devices.

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.

Lowest price in last 5 years according to triple C. Usually $500. This model is hackable to become 200MHz, and will then identify as the SDS1204X-E in firmware/on display. That is a $775 oscilloscope.

This is a good price for this scope, I paid more than $500 last year. Barely used it yet, wish I waited.

Dang, I don't remember the last time my Siglent alert went off. Thanks OP. Good deal, but I went with a faster 2 channel a while back and added a Hantek USB Oscilloscope for 16 ch for probing/logic.

Based on my research you can hack this 100mhz one to 200mhz. Instruction are all online.

Siglent (along with Rigol) are what many would consider a 2nd tier manufacturer of test gear (1st tier being companies like Keysight, Tektronics, etc). They actually got their start making entry level scopes for one of the big scope manufactures (don't recall off the top of my head who).

They make good scopes for the price and are a solid choice for lower cost gear. I have this scope, their SDG2042X AWG, a bench meter (SDM3045X ), and one of their power supplies (SPD1305X) and all have worked well for me.

Thank for the advice. I'm just getting into it. Figured this will be a good one. Hope I can still hack it. Will try after I get the device.
