Dave's cheatsheet for budget oscilloscope testing

(1/3) > >>

Hi,

as Dave offered to test some budget scopes, I thought starting a new thread to collect proposals would be a good idea:


--- Quote from: EEVblog on March 18, 2013, 11:34:49 am ---I have an open invitation to review/teardown/test/play with any product from Trio Smart Cal just down the road:
www.triosmartcal.com.au
And they usually have all the stuff in stock.
The problem isn't so much getting gear, it's the time and effort it takes to review advanced gear like scopes. And that's on top of my already backlogged list of review items!
I'd love to do a budget scope shootout, it's a just a matter of finding 2-3 days free to do it.
Of course I could try a "simplistic" or "basic" comparison review of the major features, but you know me...  :palm:
But I do plan to be that rigid with my next multimeter shootout - test X features, X time limit on each one, and no tangents.

So if someone was to come up with a list of scopes, and a list of basic features they think would cover the basics, it's doable...

For the products, I would set the limit to 400$, so at triosmartcal the following products fit within this limit:


* SIGLENT SDS1102CML DIGITAL OSCILLOSCOPE, 100 MHZ, 1 GSA/S, 2 CHANNEL
* TEKWAY DST1062B OSCILLOSCOPE, 2 CHANNEL, 60MHZ, WIDE SCREEN HD DISPLAY
* UNIQUE UQ2062C DIGITAL OSCILLOSCOPE, 60 MHZ, 500 MSA/S
Missing:

* Rigol DS1052 (but Dave already has it if I remember correctly)
* Owon PDS6062S 60 MHz Portable Digital Oscilloscope
And now I think we should just collect what we would like to have tested, put together informations like available bandwidth hacks etc…

Please keep in mind that they should be available fom www.triosmartcal.com.au, see quote above.

For the Tekway/Hantek/Voltcraft model, they are all the same:

Input linearity and pulse response: http://www.mikrocontroller.net/attachment/173049/mod_input_circuit.pdf – compare with the other models.

200MHz Hack https://www.eevblog.com/forum/chat/hantek-tekway-dso-hack-get-200mhz-bw-for-free/msg91877/#msg91877


The same applies to the Rigol, but 100MHz: https://www.eevblog.com/forum/blog/changing-the-rigol-ds1052e-to-ds1102e-using-usb-the-dummy-guide/

SLJ:
I would like to see comparisons of screen shots and refresh rates/update speed of the USB/Serial PC interfaces.

Hydrawerk:
UNIQUE UQ2062C DIGITAL OSCILLOSCOPE, 60 MHZ, 500 MSA/S
is very similar to some UNI-T bench scope...

S_Prime:
Other possible entries:
OWON SDS7102V 100MHz, 1G/s
Uni-T UTD2102CEL 100MHz, 1G/s
