Hantek DSO5202BM: The problem with using cursors Track mode.

Oleg10011001

Detected abnormal work cursor in Track mode when the oscilloscope is working with two windows. Firstly, a pair of voltage measuring cursors are always absent in the upper window, regardless of which of the window is active. I think that all four cursor must be present in both windows (when possible) ... Second, a pair of cursors measure voltage is present in the lower window does not work correctly when the lower window is active; they do not follow the curve of the signal, and sometimes one of the cursor may disappear from the window. In addition, the partition between the two windows, which indicates the setting of the lower window is sometimes packed with graphic debris; probably its normal contents are not always drawn in time.

For exemple:




P.S: Sorry my bad english.

Dir sir,
Please cilck "Utility->System information" and give us a screenshot to study.

After closing Sys Status window occurs damage information in the separator between the windows:

Incidentally, System Information window somehow disappears from the screen when you connect the flash drive, as well as by pressing the "SAVE TO USB" button. Thus there is a corruption of the information in the separator between the windows:

I also drew attention to the fact that in the upper window is not a channel marker.

It turns out that the problem with cursors work in Track mode occurs when the oscilloscope and works with only one window. For example, catching a desired waveform immediately after that I normally use cursors in Track mode:



Everything is fine. However, if I slightly change the scan time and begin to cause problems in the cursor  in Track mode:





The problem only arises if I caught the desired waveform capture of oscillograms stop further and continue to work with the waveform stored in the memory, stretching to see fine details. If I do not stop the capture of oscillograms, this problem does not occur (when only one window).

Dear sir,
We had send the latest firmware to your email.
Please check.

Well, after a firmware update, I see that the problem with cursors work in Track mode - almost solved (99%). There was a small cosmetic flaw: immediately after switching to Track mode, a pair of cursors, the measured voltage is not attached to the waveform and exhibited visible on the last stored position or just the bottom of the screen. However, it is worth a little move the cursor one measure the time and the position of the cursor associated with it measures the voltage is normalized and it is attached to the signal curve. I would like to measure the voltage cursors automatically be attached to the waveform immediately after switching to Track mode. This betrays a complete form Track mode. Now it does not look complete... Next, let's see what else was at work fixes the oscilloscope mode with two windows. I see that more damage does not occur in the separator between the windows when I close the window SysStatus and SistemInformation usual way. However, I have already said that there is a sudden disappearance from SistemInformation (and SysStatus) window screen when I connect the oscilloscope to a flash drive or click "SAVE TO USB" button. Obviously, this should not happen, but it still happens with the contents still deteriorate in the separator between the windows. In addition, the top window is still no marker channel.

Well, after a firmware update, I see that everything I described in the previous report defects were not corrected. Maybe you want to illustrate the flaw in the cursors measure voltage in "Track" mode, the type of cursor measurements. So, like so cursors appear when switching in the Cursor type "Track" mode:



As can be seen, initially measuring the voltage cursors are not attached to the waveform and measure is not clear what. This is the cosmetic defect. Should I just move my cursor "S" or "E" followed by the associated arrow cursor related to the measurement of the voltage takes place allotted to him on the trace:



Then cursor measurements are operating normally. However, if you turn off mode cursor measurements oscilloscope probably remembers the position of the cursor related to the measurement of voltage and the next time the cursor measurement mode to "Track" without looking puts cursors measure voltage at the places where they were in the previous session, cursor measurements. The problem here is that between the previous session cursor measurements and waveform current session could be shifted, and in the end this is what happens:



Here, too, enough to move cursors "S" or "E" and the associated cursor related to the measurement of the voltage takes place allotted to him. It also happens that after stirring of the cursor "S" put them to the place occupied at once both cursors measure voltage. Described defect occurs only once after the switch in the type of cursor measurement mode "Track" and disappears after the start of the use of cursors. To remove this cosmetic defect, it is necessary that when you switch to cursor measurement type "Track" mode cursors measure voltage immediately be installed in the normal position, corresponding to the current cursor position "S" and "E" on the waveform.
