New Hantek DSO2X1X models?

Hi. Newbie here :)
I've seen this question asked several times, but never saw an answer.
If you update a C10 or D10 to a D15 using dso3kb_2D15_conversion.upk
has anyone confirmed that the bandwidth does actually change to 150mhz ?
Are there any revisions where that doesn't happen?

Thanks.

Damn good question.

Keen to see any replies (especially with screen shots)  :popcorn:

I can only see a few ways to manage the BW difference between these models:
1. Through the bill of materials - kind of stupid considering they currently only appear to produce a single PCB/BOM to cover both the C/D variants. In this case we're SOL with the SW hack.
2. Switchable hardware in the analog path - looking at the reverse engineered schematics, there's no indication this HW exists. If they've done it this way the SW hack should give you full BW.
3. Implement it using signal processing to give the impression the analog bandwidth is less than it actually is - possible but requires extra code and is probably more effort than they're prepared to put in. If they've done it this way the SW hack should give you full BW.
4. The 20x10 and 20x15 models have the exact same BW spec and they simply package a 100MHz probe with the 20x10 scopes and a 150MHz probe with the 20x15 scope - hmm, cheap, easy and quite frankly the sort of approach I'd expect Hantek to take!

My money is going on option 4. Just go buy yourself a couple of 150MHz probes to replace the 100MHz one that comes with the C10 or D10

good day. Who will be able to remove the KEY_SCAN_DATA, KEY_SCAN_RESET, KEY_SCAN_CLOCK lines on the lane with an oscilloscope with and without a front panel connected?

Why?
