Hantek DSO5202BM: reference waveform.

Oleg10011001

1) Why can not I make a reference waveform from the width of the entire screen? It turns out that part of the waveform on the screen located, but hidden under the menu for some reason is not stored in the reference waveform and the result is not effectively used the large width of the screen, for example:

As you can see, the reference waveform takes at least 85% of the working area of the screen width ...


2) Several times encountered that could not save the waveform stored in the memory as a reference. By pressing the appropriate function "SAVE" I hear the sound of the button is pressed, but the message confirming the preservation of the waveform does not appear, and it is not actually saved. Terms under which this problem occurs is not yet defined. While I can only say that the re-capture of the waveform using the buttons "AUTO SET" resolves (perhaps only temporarily) the problem. I noticed this problem when the oscilloscope has already worked for some time. In general, the function of preserving the waveform as a reference sometimes works normally, but sometimes for some unknown reason stops working.

Dir sir,
About the second problem, after testing we didn't find the same problem. Please tell me how ...

This problem occurs not always. What specific actions lead to its occurrence is still unknown. I tried to get her recreate, but I have not yet succeeded. As soon as I learn how to recreate this problem, I'll tell you about it. While I can only say that this problem is sometimes, because he suddenly faced with her 3 times.

Well, after a firmware update, I see that now the reference waveform covers the whole width of the screen. Did this fix the second of these problems in the first message - Do not know. I also see that was fixed a bug in the filter settings, described in the next topic. Thank you!

However, I do not understand why when you open a menu and then when it is closed shifts the waveform on the screen? I such did not see anywhere else ... In addition, in some cases, this creates an inconvenience for those who are used to that when a menu screen contents remain in place.
