I cannot find the MSO5074FG on your latest firmware page. Where can I find the firmware for this oscilloscope?

Dir sir,
Please enter into this link to download MSO5074F(G) Firmware: http://hantek.com/en/Produ ...

Thank you. You must have updated the page very recently, when I checked the page yesterday there was no firmware on the page, only the windows software/driver and manual.

Please tell me, can you provide a changelog (list of changes) with this firmware update? I have been experiencing triggering issues (simple square wave, trigger is in the middle are of the waveform, rising or falling edge) it has a LOT of trouble triggering when set to "normal" instead of "auto"

In "auto" it seems to trigger fine, but will of course refresh the display when there is no edge (which is expected).

Hello again -- I once again do not see firmware for this oscilloscope on the page. Only windows software and windows driver.

Is there an update after 160630.0? The trigger issue is frustrating; adjusting trigger is buggy when in "normal" mode.

e.g. if input signal is 1V P-P and trigger is at 3V with normal settting, naturally there is no trigger (trigger threshold is too high). However, rotating trigger level dial slowly to reduce trigger voltage does not work. You must rotate dial quickly which leads to big jumps in trigger level. It is impossible to adjust slowly and carefully.

Also, I see no way to adjust horizontal probe offset/skew (i.e. connect ch1,2,3,4 to cal input, each channel will be offset from others a little bit, most scopes have a way to adjust each channel left/right to line them all up so they are exact. LA also has no way to correct skew with analog scope inputs.

One other bug I found in the scope firmware that I forgot to mention.

If I have a waveform on the screen with cursors (time) and I stop acquisition with run/stop button, if I try to move cursor around the trigger waveform disappears!

It would be nice to be able to freeze the waveform and move cursors around to make measurements
