Budget 3in1 - 120MHz Oscilloscope Multimeter Signal Generator

[HenrikOlsson]

Yeah, once upon a time those boat anchors were the ducks guts. When I got into the electronics hobby in the early nineties I could only dream of having an oscilloscope, even the cheapest/simplest 20MHz ones were way out my teenage budget.
Now on my shelf I have a Tektronix 2465B (4 channel, 400MHz) which by many is considered to be one of the best "portable" scopes ever built. Price in 1990 $13k or about $31k in todays money. I payed a few hundred USD for it 10 years or so ago.

I basically never use the 2465B though. Whenever I need a scope I go for one of the digital. What you can get in a scope for a few hundred bucks today is just increadible.

I am a fan of such devices. I own a DSO203 (2ana+2dig channel pocket DSO) which works well till about 2MHz and is suitable for my kind of work with PIC and other microcontrollers. I cannot do any analog / accuracy needed type things with it, but allows me to scope signals for shape and amplitude. It too has a signal generator built in. You may argue, that it is a toy. Yes, indeed! However, the convenience is unbeatable when you can carry your DSO in your pocket. Another speciality of this scope is that it is FOSS. I have contributed to the source code in a small way. Multiple versions of the firmware are online and you can choose which one suits your taste.

Another mid-range between pocket and desktop scope I own is the JDS2022A from jinhan. This runs 20MHz analog bandwidth. However, it is a power hog as it uses relays for selections.

This budget 3-in-1 scope looks very tempting except they don't ship to India anymore. Else, I would certainly buy this as another tool in my cupboard.

Counter argument would be - with so many PC scopes available, why would anyone buy such a device. Well, you cannot beat the convenience of having a self-contained DSO with battery power for one.

Anyway, thanks for asking this question. Got me interested in this.

Holy moly!

The western world had better get their proverbial butts in gear. China is coming at ridiculous speed.

I'm most likely going to get one of these, probably the DOS1104:
- 100-349 MHz
- 7 inch screen
- 4 channels with probes

I don't know enough to comment on the other specs, but this is way more practical to use than my ginormous boat anchor of a BK Precision scope.

We are being seriously left in the dust by China.

Please don't waste your money on unknown or no-name brands.

Not even close to Han...something...

I can understand the price difference, but Rigol and Siglent has done miracles on Osciloscopes.
