To add to this thread I recently purchased a DSO154pro mainly to see how the lower spec no battery version would perform. I hoped there would be a simple hack to increase the 1Mhz bandwidth spec to the 18Mhz claimed for the battery version. Turns out that the lower spec no battery version appears to be identical to the 18Mhz version. My unit had no difficulty displaying a 15Mhz sine input. It appears then that the lower 1Mhz spec for the battery version may be a strategy to encourage the purchase of the more expensive version?? Another thing I was keen to investigate was the possibility of adding an 18650 Li-Ion battery to my unit. Again, it appears that the "no battery" version is identical to the more expensive DSO as my unit has a 2 pin socket for a battery and an 18650 cell scavenged from an old notebook battery was able to be connected to the socket and charged via the USB C power input. As Dave would say - "winner winner chicken dinner" ;D As others have commented the DSO154pro is a pretty basic unit however it significantly exceeds the performance of the 200Khz DSO138 for much the same amount of money. With an 18Mhz bandwidth, a max 50ns timebase, variable persistence, roll mode, and inbuilt 0.01Hz to 500Khz function generator it has been a lot of fun to play with. |

Anyways, if it were able to a single channel is all that's required for decoding UART. Did so today as a demo to a customer. |

An update on the DSO154pro - after putting the function generator through its paces my unit topped out with a max frequency of 1Mhz. Twice the claimed 500Khz spec. |

I got the one with the battery and real probe. :popcorn: The 'scope will be very useful at Arduino club and the siggen is icing on the cake. Seems like a bargain for 32 Euros (shipping included!) |
