FNIRSI® DPOS350P 4-IN-1 350MHz 1GSPS Tablet Oscilloscope Signal Generator Spectrum Analyzer Frequency Response Analyzer

DPOS350P Works fine, but battery capacity is significantly lower than advertised

The functionality is really good for such a small device. It would even be better, if it would have some sort of serial protocol decoder functionality. The device description doesn't claim that, so it's not a negative. I'm just missing it. The real negative thing is the battery capacity. It is advertised as 8000mAh. But multiple full cycle discharge/charge measurements (with FNIRSIs own FNB56) reveals only 6300mAh. Also couldn't find the correct signal generator output impedance (it's definitely not 50 Ohms). The documentation doesn't tell you either. A really good thing is the possibility to take snapshots and the easy methods to review them on the PC. Very nice for documenting field measurements.

Top!

We are happy with this oscilloscope. Fast, good screen and strong battery. The only thing is that the ground is common to both ways. But in automotive application with students it’s ok for us.

DPOS350P excellent price/quality!

The DPOS 350P that I recently purchased from FNIRSI is a very successful product, robust, with a large screen, many functions, easy to operate, built from quality materials and yes I am delighted with this purchase, thank you to the FNIRSI team. I highly recommend purchasing this product.
