@BTO
I have some questions about using the MSO5000, which I ask you and other colleagues to repeat the test and help with the solution:
1. Measure SlewRate of a Square Wave Signal.
Connect the MSO5000 GI to CH-1, with Square Wave and f=1MHz, and Amplitude = 1Vpp.
See the IMG, notice that the SlewRate Measurement is in the unit of (Mv/s).
It turns out that the SlewRate unit is (V/us) and the MSO5000 displays (Mv/s).
Besides (v) is in lowercase and should be capitalized (V). The (Mv) means (Mega Volt) which is a very large number, and at the bottom it shows (s) which means (seconds) and should be (us).
I was unable to change the Unit of SlewRate in the MSO5000 menu.
Check how to resolve this.

THIS IS A VERY VALID POINT
k = Kilo = LowerCase "k" (According to S.I. Units) and it follows that
V = Volts = Uppercase "V"
s = Seconds = LowerCase "s"
m = milli = LowerCase "m"
M == Mega = UpperCase "M"
and even by comparison the Vpp and Vavg are measuring in uppercase V, YOU ARE CORRECT
there is no setting for this,
I have forwarded this onto a senior Engineer at Rigol who is currently taking all this very seriously, and IT WILL BE ADDRESSED, don't worry.
I just don't have a date as to when it will be,
I know they are going to look at it tomorrow, but this needs to be fixed in a new firmware update and given that now we have 125 issues to fix.
i don't know exactly when it'll be, but i'm happy to keep you updated.
so that's all the problems sorted.

Hi,
Dear @BTO,
Thank you for commenting on my doubts.
I put my questions here, because luckily you have good contact with a Rigol Engineer, who can answer the technical FW and UI questions raised by MSO5000 consumers.
Yes, I agree with you that:
“Re Problem 2 and 3 - IS NOT A PROBLEM, ALTHOUGH I CAN SEE HOW IT WOULD BE CONFUSING.”
See that I put the entire procedure here, so you and other colleagues can reproduce the test.
I suggest that the Memories (Ref1 -> Ref10) are numbered in the UI as (Ref0 -> Ref9), This will maintain the logic of all files saved in Drive (C).
I saw that you were able to place (ALL) the IMGs saved in Drive (C) on the screen at the same time, and also in the (Ref) Table.
@BTO, but in practice this is not necessary.
For example, see that you can make a sequence of Waveform Measurements of many signals in one (Radio #1). And save in the Table (Ref) and in the Drive (C). To then compare with other Radios identical to (Radio #1), to adjust, for example, IF Coils, RF Filters, etc...
See that you have in Drive (C) the IMGs of interest to adjust everything you need, and you can transfer them to the table (Ref), to use (ONE AT A TIME), and not all at the same time. You only need (1 IMG at a time) to make the comparative adjustment.
And then you do one (Press -> Default) and delete the entire Table (Ref), and do other things of your interest.
On another day, you take a different model (Radio #2) and do the same procedure. And you don't have to worry about numbering, as the MSO5000 does automatic and sequential numbering, starting from (RigolDS0 -> RigolDS1). You just need to have external control of what was saved in each position of the (RigolDS x)... Or change the name of each one, in each operation.
But imagine that you have 200 or more IMGs saved in Drive (C) of many Radios and other Equipment, I think it is better to leave the automatic numbering of the MSO5000.
And one fine day, you have a model of (Radio #2) to adjust.
It's simple, you can load 10 IMG at a time, in Memories (Ref1 -> Ref10) and you are ready to adjust (EACH ONE) of the adjoints, step by step, and the screen has to have (1 IMG at a time), and not the ones (10 IMGs at the same time).
See that if you (Press -> CLEAR) you clear the screen of all IMGs, and what I want is to sequentially select the IMGs from (Ref1 -> Ref10), (ONE AT A TIME), and do a comparative test, and adjust your copy of (Radio #x) as it is in the IMG of Ref.
But the MSO5000 UI does not allow you to load just one IMG, for example (Ref3) on the screen. Check.
Another idea, imagine that you are in a small artisanal factory, where you have (10 Adjustment Stations), with different people or operators. And each (Adjustment Station) has an MSO5000 loaded with a single Reference IMG (Refx), each operator makes an adjustment, and see that productivity will increase a lot, as well as the quality of the adjustments.
@BTO, notice on your MSO5000 that the UI does not give you the option to load (1 IMG) saved in the (Ref) Table. You load (10 IMGs), and have (10 IMGs) at the same time, but you can't load just (1 IMG). Some (BUTTON) is missing from the UI. Check out.
In the hypothetical (Adjustment Station), it is impractical to have (10 IMGs) on the screen at the same time for the Operator to choose (One), and compare with a signal of interest on a board.
To be continued.

Hi,
Dear @BTO,
To explain better, and you understand:
You stated that:
“Anyway, it all works, I think you just didn't use the IMPORT option”
Check my msg #62, in (item #4) that I used the (IMPORT) function to bring the IMGs saved in Drive (C) to a position in the Table (Refx).
The central issue is that you can IMPORT (10 IMGs) saved in Drive (C), and load them into Memory positions (Ref1 -> Ref10). But you can't use it (ONE AT A TIME). Check out:
(Press -> CLEAR) and try running just one IMG saved in the (Ref Table).
As for your message #65, you understood my question regarding SlewRate measurement, and forwarded it to the solution. It's great that you were able to open this solution channel with the Rigol Engineer.
I have other similar UI questions, in the Bode Plote and FFT functions. I will produce a coherent text, and post it here for you and other colleagues, to see if there is any viable solution.
Much obliged.

- No problem
--- Quote ---See that I put the entire procedure here
--- End quote ---
- Yes i saw that, Thank you
--- Quote ---@BTO, but in practice this is not necessary.
--- End quote ---
- of course not, i was just finding a solution for you
--- Quote ---And then you do one (Press -> Default) and delete the entire Table (Ref), and do other things of your interest.
--- End quote ---
- The other thing you could do that would be better would be to create a .stp (Setup File), You customize your scope, then you create
the setup file and then just reload the setup when you're ready, Or.. You could hit Default then setup.

- YOU CAN.. i've got a video coming, don't worry

--- End quote ---
- YES IT DOES
--- Quote ---@BTO, notice on your MSO5000 that the UI does not give you the option to load (1 IMG) saved in the (Ref) Table
--- End quote ---
- NO.. it does allow me to load only 1 image
--- Quote ---You load (10 IMGs), and have (10 IMGs) at the same time, but you can't load just (1 IMG).
--- End quote ---
- NO, i chose to load that many images, But i can load 1 or 3 or 10 as i choose, Just use the IMPORT selection
--- Quote --- Some (BUTTON) is missing from the UI. Check out.
--- End quote ---
- Which Button is Missing ?
--- Quote ---In the hypothetical (Adjustment Station), it is impractical to have (10 IMGs) on the screen at the same time for the Operator to choose (One), and compare with a signal of interest on a board.
--- End quote ---
- I Agree, but in that scenario each operator CAN have ONLY 1 Reference waveform loaded.
