New Hantek DSO2X1X models?

<< < (301/388) > >>

DavidAlfa:
I'm about to order new encoders.
After thinking it twice, I'll avoid the mechanical steps in the small encoders, adjusting certain values require a lot of turning, dealing with a ton of clicking will make the experience even worse!

So the idea is keep it just like it is now, but with more steps per turn to make it less painful, and decent quality parts.

The PEC12R-4220 (7mm shaft) series are a direct replacement (As we already know, thanks to pu6k1n and vistorik :)).
If not being able to source them, the PEC12R-4225 (12mm shaft) will almost fit, the small caps have a depth of 12mm while the large ones have 11.2mm, it would only require trimming a bit off the shaft end.

- Pushbutton + stepped rotation (Sec/div knob):      PEC12R-4220F-S0024 / PEC12R-4225F-S0024
- Pushbutton  +  smooth rotation (Small knobs):      PEC12R-4020F-S0024 / PEC12R-4025F-S0024
- No pushbutton + stepped rotation (V/div knobs):   PEC12R-4220F-N0024 / PEC12R-4225F-N0024

Also the PEC12R-3x series will also work, it's the same P/N, just replace the 4xxx with 3xxx.
The difference lies in including a bushing.

The shaft offset is 2mm larger in the PEC12R-4222 and PEC12R-4230, so the knob sit 2mm away from the base, though still possible with additional modifications to the shaft.
The difference can be seen here:

I am replace FPGA with GW2AR-LV18EQ144PC8...
After the replacement, the buttons became work, the calibration passes but the Auto mode does not work, + incorrect data in 1GSa / s and 500,
Has GW2AR-LV18EQ144PC8 been used correctly or should GW2AR-LV18EQ144 be used without P
or such GW2AR-LV18LQ144

DavidAlfa:
I think the SDRAM will be too slow?
But I have no idea about the exact FPGA model..

alias095, the best is to ask Hantek (Han Zhangqiang, Email: zhangqiang@hantek.com) to sell you a native FPGA LEMONTREE chip of the corresponding series (numbers under the name of the chip) with an explanation of the reason. Maybe they will sell it to you. They once sold me separately a new DSO2D10 motherboard.

Cihan:
Is it worth buying DSO2D10 in 2023 or should I be looking forward for some other 2 channel model under 300 bucks? 4 channel is preferable if I could find one below 300 USD. By the way there are many oscilloscopes with 2Gpts memory depth today but I have no idea when they'll be under 400 USD.
