Hello everyone!
I'm brand new user of DHO924.
First impression - it's great small, but capable hobby/education class machine. If I get information from this forum before I bout it - probable I'll choose DHO914S
First impression is always critical and easily highlights usage gaps.
My suggestion is:
1. It's a lot of waisted space on the screen - it's not so small, but lot's of space waisted with useless borders - in my calc - near 3% horizontally and 6-7% vertically just waisted.
2. window-type interface isn't fit instrument-like interface. Why I cannot place math traces on the same screen, as main channels? In most cases I want to compare channel input with calculation on other signals - it should be configurable how to present match results. Again, window borders usually just waist space rather than show additional info.
3. Fan noise really annoying - taking in account constant power consumption in any mode - they just switched off all power saving features - probable to get better real-time response, but why we need acquisition and real-time calculation for example in single trigger mode? Suggests to switch off ADC after capture - it will not influence any functionality, but save power, especially if try to use scope with power bank.
4. Text label size should be configurable
Overall impression - MSO5000 screen stile much more useful.
Found errors:
First run of cursors after switch ON always show maximum brightness. only after visiting display settings it's become as it where set.
Window transparency did not remembered in settings.
Navigation function works very strange
![Confused :-//](https://www.eevblog.com/forum/Smileys/default/confused0024.gif.pagespeed.ce.5xOqKkq0Co.gif)
- in "time" mode - step time not indicated
Search on/off switch located on the second layer of config - If I'm switch it on, than close this window - navigation arrow disabled, but screen still showing zoom and search events points. To switch off this screen, need to activate navigation again, go to search and switch it off.
Only screen buffer seems to be searched - even in Stop mode.
To search the edge - threshold value restricted on strange level - full screen 0-3V, trigger at 2.8V, but search threshold is restricted to 361mv, no matter what edge to search.
Hope RIGOL will read it.
