FNIRSI 1014D Digital Oscilloscope Dual Channel Input Signal Generator 100 MHz 1GSa/s Sampling Rate 7" TFT Display 240 KB Storage

does exactly what's advertised ...

Good product

Not soo aqurat but worth for money

First of all don't mistake it to high end scopes. Measurements may be off by 5-10% and it's overrated sampling rate advertised and has small waveform storage buffer and limited trigger options and depth. But scopes that have all these cost 3x to 7x also. But good enough for waveform analysis for beginner and general purpose work up-to 20-30 MHz. Display is beautiful. Starts up quickly, No waiting. Probes are sturdy. USB Power supply is isolated which is great in certain situations to prevent ground loops e.g troubleshooting mains connected SMPS etc. You can even use 2A output USB power-banks to be doubly sure. This also gives possibility of field work where safe mains supply may not be available. The power supply is strictly 5v and is very noisy. Better use a apple power supply or power-bank when you want cleaner waveforms for triggers. Many bad reviews about display not working and signal generator failure come from people who plugged it into 12v barrel connector on their desk by mistake. Best is to hot-glue the power-cable to the scope to avoid this very common mishap. Even if it happens not everything is lost if you realize instantly and disconnect. Just replace the PT4103B LED driver IC in the rightmost metal case for display resurrection. Alternatively you can also use a boost converter board and inject 8.02v+ into Schottky diode S534. If your firmware is corrupted and scope does not boot you can get a workable firmware from sites like EEVblog and custom write it (not just copy) on to new SD card of exact same capacity (higher capacity may never work). If paranoid you can save a disk image of original SD card as its encrypted. You probably never ever need to come this far if you use it with due care for basic tasks. I put it up because few people get stuck. Also don't get frustrated by many sponsored reviews saying this scope is totally useless and sell it in scrap!! Happy scoping :D

Just purchased and is performing satisfactory. Worried about just 15-days warrantly. If product fails after that then what?

Het toestel is nog veilig in gepakt in de originele verpakking tot dat m,n werkplaats is aangepast . Nadien wordt het toestel uitgetest en gebruikt voor wat het toestel is ontworpen .

User interface is intuitive and display is clear. Tested up to 30mhz and all seemed reasonably accurate.

It delivers.

Perfetto nella spedizione. Lo strumento non arriva a 100 Mhz, ma era un aspetto conosciuto. In rete si trovano diverse recensioni che descrivono le caratteristiche dello strumento. È perferto per un hobbista, e per chi nonnlavora in alta frequenza (dino an39 Mhz ci arriva, poi taglia troppo). Il generatore di segnale incorporato funziona bene ed è utilissimo (sempre per uso hobbistico). Per utilizzi in b.f. è ideale (es.: nel campo audio)

Has been my standard at my desk for an year now. Does things reliably well for good complexity hobby level work. No CH1-Ch2 math. Has XY plotting option and has a rudimentary spectrum analyzer too. Signal gen can only do ac signals. But that is easily dc coupled and usable. Great value for money. Works very well.
