USB oscilloscope advice

[yoga]

...and brought me the loto oscilloscope the osca02 one, but it's not going to be here for a while ...
if there is anything anyone wants to know about it just ask and I'll try and give information on it, as this will be my first oscilloscope please be patient with me lol

Well, I have a simple question: Does your plain LOTO OSCA02 work with an android tablet or phone once connected via OTG adapter ?

And did you get the OSCA02 or a different one like OSCA02M which is the official version that supports android and comes along with an otg adapter and a full hscope licence ?

I am asking due to the modularity mess and complexity of the whole Loto line up which you can see here in its full glory of pricing on aliexpress for EU incl. 19% VAT per end of february 2022.

OSC482     65,67€
OSC482L    78,79€ = OSC482 + 4 channel logic analyzer
OSC482M    86,45€ = OSC482 + Android hscope licence + OTG Adapter
OSC482S    90,83€ = OSC482 + signal generator (on banggood just 16€ incl. shipping)
OSC482X   103,96€ = OSC482 + signal generator + 4 channel logic analyzer
OSC482F   124,74€ = OSC482 + signal generator + 4 channel logic analyzer +  Android
OSC482D    98,49€ = OSC482 + differential isolation module (but only 1 channel free - so better to get the owon vds1022i)
OSC482H   158,67€ = OSC482 + signal generator + 4 channel logic analyzer +  Android +  differantial isolation module

And your OSCA02 offers even more combinations of those letters / modules if I remember right.

MOST IMPORTANT:
some of these modules can be purchased later and used like the signal generator that you can get for 16€ from banggood.
BUT other modules like the Logic Analyzer can be purchased too without being able to work unless you ship your device back to the manufacturer where it need to get a new firmware. But no one ever will do this due to shipping prices so you need to be very aware and taught what loto model you purchase if you buy a loto cause otherwise you end in a trap and need to flip the old for the new right one.

And as you can see you can get the OSC482L for 80€, but if you want Logic and Android your have to spend +45€ more or roughly 55% even though you would only need the otg adapter (i already have like many others having raspberry pi zeros) and a free hscope app or the 12€ paid full licence, so 35€ spend for nothing cause I do not need the signal generator and a otg adapter for 35€.

So far I could not find out if any of the non 'M' editions will work with hscope and therefore I hope you might tell us soon if your basic OSCA02 will work with an android OTG capable device out of the box like my hantek 6022BL did and the owon vds1022i, just by connecting and installing the free hscope app from the google play store.

I also hope that other loto osc interested will find this topic in their search list who are struggling in the loto modularity universe who are in need of a logic analyzer module and have to buy the osca02L or osc482L cause those need to get the right firmware in the factory to get the L module working.

thanks for sharing the story  and talking about the sad fate of your child walking ahead to the other side.
might help others too !

I have been using Analog Discovery 3 for 2 years and am very happy with it.
It is a bit pricy but comes with many functions like 2 ch oscilloscope, 2 ch signal generator, spectrum analyzer, network analyzer, power supply, voltmeter ...
Easy to to write scripts

In 2017 I bought an Owon, then replaced it with a decent standalone and could not stand the noise of the inbuild fan.

I've got a PicoScope 2204A now and am thinking of replacing it with the 2205A. Although only doing audio work I am running into limitations with the build in 100kHz AWG (want higher frequency and the square wave can be better).

The software differrence with the Owon is like night and day.

The signal generator on the 2205a has identical specs as the one one the 2204a.   I would expect it has identical performance.   Are you sure it won’t have the same jittery square wave problem?

I have the 2204a and purchased an eBay function generator to get better signals.
