Just tried the last Firmware (2019060601), what were the changes on it? It would be nice to have a change log provided with the main changes between the different FW version.

Anyway, I will try it further to see if it has any improvement, for now I can tell you already it has a new bug: connect the oscilloscope to the USB, when it is disconnected you will see the battery level indicator flashing in red, as if the battery is low, even with the batteries fully charged. Turn the device on and off again and the icon will show the correct battery state.

Здравствуйте. Почему после обновления FPGA меню новое добавилось при включении аппарата.
И в sys info пишет что модель Hantek K2C82, а должно быть 2c42 ?
При нажатии кнопки меню выходит на самом деле меню.
Это нормально или что-то пошло не так?

Sir, I didn't reproduce your problem.
Please give me a video to study.

Sir, do you mean the model in the system information is different from that in the front panel?
Upgrading the FPGA will not change system information。

Please give me the serial number under the bracket.

Where did you download the firmware files you used to upgrade?
Firmware file you used to upgrade does not match your oscilloscope.
Please download firmware in the third reply to this post to update.

Hi Amy, Dmitrkov already posted a video, so he can reproduce the problem as well.

I've noticed the issue with the charging status icon in FW 2019050901 and 2019060601. To reproduce it, just connect the device to a USB port in a computer or the wall charger while in scope mode. In DMM or AWG mode de icon status works normally. When the cable in disconnected, the battery icon flashes in red, even with the battery full.

Another bug that is older (I've reported it some time ago, but probably went unnoticed) and I think is more critical is in AWG mode. With the "Gen out" disabled if you use the virtual keypad to enter any parameter of the waveform, when you exit from the keypad the output of the function generator is activated, but the status icon on the display and the led in the play button still indicates it as off.

To try this, set the device to AWG mode, connect "Gen out" to an oscilloscope so you can see the output. Make sure the output of the AWG is off, now press, ie, F2->F2 to open the virtual keypad (works in any parameter), enter a value or just hit enter to exit the keypad. You will see in the oscilloscope that the output is now activated.

If I have some time later, I can try to make a video to ilustrate, but I am pretty sure it is very straight forward to reproduce these problems.

2C42 with FW 2019060601 and FPGA V4 the Stop Button in Scope Mode doesnt work.

you can test it when you start a longtime Measuring with Timebase 2 Seconds and Forced Trigger and do press after a few seconds the stop button. the button goes immediately red but the measuring dont stop until the whole memory ist full.
