What are the exact differences between the Velleman HPS140i and the HPS140MK2?
Ok thank you I’ve managed to compare the three handheld oscilloscopes: HPS140i, HPS140MK2 and HPS50:
The main differences between the two is that the HPS140i runs on internal battery and requires a 9V charger, while the HPS140MK2 runs on 4xAAA batteries. What I don’t know if you can use rechargeable batteries on the MK2 and charge them right away in the unit, that would be awesome.
Also, I think the screens are different, one is TFT or LCD with backlight, and the MK2’s is OLED-like, since there’s PWM for screen brightness that you can see flickering when you record it with a camera.
