Hacking the Rigol DHO800/900 Scope

[norbert.kiszka]

AndyBig, don't do this changes so quick, because we soon will be competition for Rigol with our own scopes made from scratch

Anyway, good idea. Looks very useful to me.

works perfectly, many, many thanks.

The panel with measurements is now without a background and all items in it are pressed down. This allows you to see the oscillogram better when only 3-4 measurements are active.

Very nice. Maybe you could push the measurements up by a few pixels to avoid overlapping the time scale.

[ebourg]

Another suggestion for the measurements: what about removing the channel indication "(C1)" and instead painting the label (Vmin, Vmax, etc) in the color of the channel? That would save a few pixels horizontally. Also the down arrow could be moved to the same line as the text, that would reduce the height of each measurement.

Do you mean to raise the measurements so that this area does not overlap the readings on the time scale?

Yes, coloring the dimension name and removing the channel name is a good idea, I'll try to implement it.
Regarding the arrow - I was actually thinking about removing it from the collapsed items. Now the item is expanded by tapping on the right side of the item, it is not necessary to aim at the arrow. But in the expanded dimension, I was thinking of leaving the arrow for collapsing.

You could remove it as well, once it's understood that tapping expands/collapses the items the arrow becomes useless.

Regarding removing channels from measurement result headers and coloring the headers in channel colors.
In single-channel measurements, this looks fine, as in the top item on the screenshot. But what about measurements involving two channels, as in the bottom item on the screenshot? Color the parameters as in the middle item? Won't this make it difficult to quickly read the results?

You could remove it as well, once it's understood that tapping expands/collapses the items the arrow becomes useless.

In the expanded item, you still need to designate the area that you click to collapse Besides, the size of the expanded item is already quite large, an extra 5 pixels will not play a big role.

[RAPo]

Could you keep the channel text in white and underline it with a coloured bar that represents the channels?
As for collapsing/expanding, could we agree on that the right area of a measurement item is for collapsing/expanding I think the arrow can be removed.
Without an arrow, the looks are cleaner also when you take a screen capture.

[AndyBig]

Well, in principle, it can be read quite well on the oscilloscope screen.

[norbert.kiszka]

This arrow gets half of the vertical space.

Probably yes, but it won't solve the problem with channel designations in two-channel measurements.

In the expanded measurement item, to collapse it, you need to click not just on the right, but on the bottom right. Therefore, it seems to me that it is better to leave the arrow in the expanded item

This arrow gets half of the vertical space.

Yes, but you shouldn't make them too narrow either, otherwise it will be difficult to hit the element with your finger

[AndyBig]

These are probably the minimum sizes of measurement elements that still retain fairly easy readability.

FTP not interesting.
MyPhoneExplorer does it much comfortable.

[norbert.kiszka]

Some time ago I did automatic downloader for FTP in this scope, to periodically download new files. However it was written in "ugly and old" PHP language:

https://github.com/norbertkiszka/Sync-new-files-from-FTP

Why I have to download it manually every time, when I can make some 5 minute code?

[Terry Bites]

I think I have navigated the mega jargon bomb of this thread. Maybe.

I still cant figure out the meaning of " Send the DHO900-BODE and DHO900-BW15T25 options from those generated in step 3 via the SCPI interface".
I can see how to create these files.
What does 'send' mean in this context and how do i do it?

What happens if it all goes pearshsped. Will I brick my scope?

[TheoB]

Connect your scope to your lan network. Enter the IP address in your browser and you will see the LXI interface. There you can send SCPI commands (and control the scope remotely or make screenshots.

Added text outline to channel labels for better readability against a dense signal background.
The screenshot shows before/after.

I did everything according to your suggestions, they were good ideas, thank you Only in two-channel measurements I had to change the letters to capital letters in the measurement types ((f-f), (f-r), etc.) so that their color would be more visible. And the letters themselves are now easier to read.

One thing to keep in mind when using only color to indicate something is how that might affect color blind people.

It looks nice, thank you for implementing this. There is just a contrast issue with the CH4 dark blue on the grey background.

Did you try to completely remove the background and the rounded border?

Excellent point. I completely missed that...

Yes, the color of the fourth channel looks very low-contrast on a semi-transparent background. Here you should not remove the background - then the text will be lost against the background of the signals, but on the contrary - make the background opaque black. On a black background it will be readable normally.

I'm sorry if it sounds so harsh: This is a very very bad idea!
Like 20% of the male population, I have a red/green visual impairment. I can hardly distinguish between light green and yellow on a screen, for example, and if it's only a few pixels (as with written text, for example), I even can't tell whether something is red or green.
With the specification C1 ... it is usable, without it is useless.
