I've been using a Tek 2213 for a while now. Ch1 works ok, ch2 doesn't. I've been looking at upgrading for <$100. I use it for audio stuff, low frequency, a few kHz is all I need.

Hantek 6022be Digital Oscilloscope is only $65, 20 Mhz.

Are there other USB based to consider? A stand-alone would be nice but decent digital ones are hard to find for <$300.
Thanks.

USB scopes have their place but a good bench stand-alone can't be beat with today's scope technology.

Well, that's a lot more. But I was thinking maybe a handheld stand alone would be better than always needing a laptop to use it:

Hantek TO1112 Touch Screen Digital Oscilloscope 2 Channels 110Mhz Hanheld Tablet Digital Oscilloscope

This HANMATEK DOS1102 is another one in the <$200 range. Are Hantek and Hanmatek related?!?

Also Hantek DSO2C10.

 

Hello,

@tautech , do you have any recommendations?

One with A waveform generator would be useful.

 

This ADS ?

No idea if those are related but in this case you can a lot for what you pay for with the Rigol or similar types. If you're serious about electronics, save a bit more for something that will handle most future requirements with one scope. The Rigol is powered by a USB-C connector, so portable use is easily possible.

 

Have you looked at he FNIRSI models portable/re-chargeable ?
Double Beam
AliExpress, $65.00

Not specifically rechargeable, but have been looking at this FNIRSI 1014D model. 2 ch with a signal generator.

 

I think I can guess what @tautech has to say.
I like the Siglent SDS1202X-E.
Have a look at FNIRSI 1014D.
If I were on a tight budget I would still favor a used Tektronics 2213 or Tektronics TDS210 or TDS220.

Check ebay for a used Tektronics 2213 for under $100, used TDS210 for under $150.
For the price of a used TDS220, a new FNIRSI 1014D would be a better buy.
There is YEAPOOK ADS1014D for $173 which is a rebrand of FNIRSI 1014D.

 

I picked up a FNIRSI 1013D, stand alone , nice and handy |

Always.

However when a buyer is reluctant to embrace new technologies with a better than bottom shelf budget there's little I can add.

SDS802X HD is where it's at today and for a little bit more the 4ch version, SDS804X HD and although these are 70 MHz DSO's, their feature set far exceeds anything the formerly popular SDS1202X-E ever offered, so much so we no longer stock SDS1202X-E, only 4ch X-E versions but for how much longer is the unknown, such is the popularity of the 12bit SDS800X HD series.

 

What about a SDS1052dl+ for under $200 on eBay?

Sound but basic DSO.
Limited feature set.
New or used ?

 

Used. 150+35ship.

there’s a SDS1202x-e for $243, missing a probe.

 

I have a vector network analyzer that uses a PC as the display. I thought it was a great idea. Where can I find a DOS PC with a serial port. Not a Windows serial port but an old one where the software writes directly to an address. Software on floppy. LOL

The point of this is that someday, Windows will upgrade. It only takes one update to kill your scope. The USB will go away, and you will not have a scope. The company will go away or will not support the product.

On the other hand, there is some real nice PC software for scopes.

Either are fairly priced vs new.
SDS1202X-E if your budget allows it offers a much better feature set.
Suitable probes can be found on ePay for very little yet may not provide the full 200+ MHz BW that PP215 probes do.

 

Let me reiterate my criteria:
Audio: a few kHz is plenty.
Signal generator would be useful.
2 channel.

I’m a mechanical engineer, I can’t imagine I’ll ever use most of the features on the newest model. But I appreciate that the cost diff between a SDS12xx is not much more than the 1000 series or even other brands.

2 channel.

That is a huge misconception.
You assume that since audio only goes up to 20 kHz then that's all you need in an oscilloscope.
You cannot examine a 20 kHz square wave on a scope with 20 kHz bandwidth. You need 1 MHz minimum.
Bargain basement scopes start at 20 MHz bandwidth. You should not settle for anything lower that this.
Entry level scopes start at 50 MHz or 100 MHz. Personally, I would not settle for anything lower than this.

If you want a scope for under $200, get the FNIRSI 1013D.
YEAPOOK 1013D now going for $146.

 

If you don't want to break the bank, have a look at handheld scopes, for example FNIRSI 2C23T, also HANTEK and Vevor for under $100.
