Again, this is a low end scope, make no mistake. I clearly stated that in my initial review here.
That said, it is not that "basic" and limited in features.
For those interested, please read the user guide available from Owon official website.
Some of them, verified by myself on the scope by doing some measurements, not just reading specs here and there (that is the starting point, though):
- On Acquisition modes, it offers Sample, Peak detect, and Average, Vector or Dot types, Persistence OFF, 1, 2, 5 and Infinity, XY Mode, Counter Off/ON.
- On Measure it offers up to 30 different types.
- On Cursor it offers Voltage, Time, Time&Voltage, Auto Cursor.
- On Utility, Display backlight from 0 to 100%, Graticule with 3 types, Menu time out from 0 to 30 sec.
- On Vertical inputs, AC/DC coupling, 5mV with 20MHz limited BW, 50mV with full BW, Inverted Off/On, Probe 1X/10X/100X/1000X, MeasureCurrent Off/On, Limit bandwidth Off (full 100MHz on 10X) / ON (20MHz on 1X)
- On Math, it offers Sign +, -, *, /, and FFT (both channels, six common algorithms, Vrms or dB, Horizontal/Vertical adjustments, Cursors)
- On Trigger it offers AC/ON coupling, Single/Alternate, Edge or Video (yes, some people still enjoy PAL/SECAM/NTSC (!) ), Auto/Normal/Single modes, two ramp slopes with adjustable level, Holdoff from 100nS to 10.0 sec
And before someone ask, yes, it can use a USB pen at the front to save waves and screenshots, and yes, the scope has a second USB port at the rear to talk to a PC, where the Windows remote capture and control application available for downloads from Owon official site works nicely and smooth, no lockouts or hangs or funny stuff in there. And yes, that application runs fine on Windows 10 as well. For those having this scope and not able to install the Owon app due to initial error messages, just rename the zip file to remove the chinese chars, and as for the Windows scope driver installation just follow the supplied instructions.
The best prices I can find delivered to Portugal free of additional import taxes are from AliExpress where some Chinese suppliers have European Union warehouses in Germany, UK, France and Spain.
AliExpess Spain location offers free shipping to Portugal as well, after all we are in the same Iberian Peninsula. Currently there are a few suppliers delivering the OWON SDS1102 for 190,40 EUR shipment included and no additional taxes.
The other alternatives, with better specs, are far more costly from my base location.
For example the Rigol DS1102Z-E that I had in my shortlist as well, is not available from any European locations, starts at around 230 EUR to 270 EUR all from China located warehouses, meaning that I would have to wait at very least 2 or 3 months (I have this experience importing other goods from there) and then pay custom import duties and VAT on top of that.
And the XDS3202E would cost at least 331 EUR + custom import duties on European Union.
For my needs, the Owon SDS1102 serves me well.
If I need to capture data for analysis, then I will buy an USB logic analyzer. These can be found at really low prices with decent specs.
And here is my humble SDS1102 acquiring a 110MHz 78mV rms sinusoidal wave from a vintage Heathkit IG-102S running at its top limit fundamental frequency, where the advertised feature of being able to work at 220MHz (2nd harmonic) is confirmed by the FFT humble analysis of the Owon.
