Need help hacking DP832 for multicolour option.

[Gandalf_Sr]

You can use Riglol to add LAN to a DP832 and then Telnet to it via LAN to do the model change.

[belzrebuth]

True , but I was thinking in terms of keeping all changes reversible just in case.
It's very nice that you can essentially enjoy all the extra features of the "A" variant without losing your warranty.
But I could always try the USB method and the UltraSigma software for just once.

[Gandalf_Sr]

You can change it back to a DP832 and then issue a SCPI command to remove all options.

[belzrebuth]

Oh, I didn't know that.
Great!Thanks:)

Hello.
Thanks for guy' that made an fantastic work. My news devices, bought in spring 2020, are betters whith yours reserches :     
DP832 -> DP832A - news colors but, also (must !) better définited ( mV and mA)
*IDN? -> RIGOL TECHNOLOGIES,DP832,DP8Cxxxxxxxxxxxx,00.01.16

DG1022Z -> DG1062Z - Sinus fréquency max = 60MHz ( saw with scope) and memory up to 16 MB in no limit trial mode.
*IDN? -> Rigol Technologies,DG1022Z,DG1ZAxxxxxxxxxxxxx,03.01.12

One note for DG : square waveforms aren't particulary correct at frequency upper than 1MHz ( transitions are curve !!!). Sinus at 60MHz very correct.

[Gandalf_Sr]

Zut alors jcfoto, c'est fantastique! Bonne chance.

translation...
Damn jcfoto, that's fantastic! Good luck.

One note for DG : square waveforms aren't particulary correct at frequency upper than 1MHz ( transitions are curve !!!). Sinus at 60MHz very correct.

Ι've noticed that as well on my DG1022z; one would think that "upgrading" it to dg1062z would also scale upwards how the square responds for frequencies > 1MHz but it hasn't changed much.
The relationship should be linear since the square is a sum anyways so essentially doubling the BW would also double the limit of a nice square output.
If it was 1meg before, now it should be at least double that.

I've not tested a "before" and "after" to be sure but I too think that square is the same.

With the 25MHz limit an acceptable square output of around 1MHz maybe be expected since a square inherently consists of infinite harmonics to start with and technically *any* BW is not enough to represent it but it's weird that changing the upper BW limit didn't improve the square output much (enough to be noticeable at least)..

EDIT:
I've had a problem (user error probably) after upgrading so for anyone experiencing the same it might be of help.
The peak to peak value was not consistent all the way up to 60MHz.
I had to revert to factory settings in order to have a proper voltage output all the way up to the limit.
But that did not improve the square I think.
Τhen again, the scope also has a BW limit so..
I'd need to change the model back to 1022 and take a diff measurement of some sort to at least have a reference point.

[PA0PBZ]

The specification for all the DG10* models say "Square: 1 μHz to 25 MHz" so I would not expect anything to change.

[belzrebuth]

Yes..
So it's only a higher freq sin the only difference between these models..

[Gandalf_Sr]

On my DG1062Z, the square wave output is only a square wave at 10 MHz and then the rise fall times are pretty long (11 nS), by the time it gets to 25MHz, it's pretty much a sine wave.

[jcfoto]

I'd made two recents "print screen" of my DS2202E scope ( full options !) from DG upgraded :
Sinus 59MHz -> Very little Frequency and voltage modulation. It's correct. 5vcc
Square 15MHz -> Very ... funny square signal, is'nt it ? Correct up to 5MHz. 5vcc
For hight frequency square signals, i use µ controlers ( more efficient).

On join "print screen", scales and samples of scope may be readable.

15, 25 and 50MHz square from an upgraded DG4062 on a MSOX3054:

Just an observation which slightly worries me.

After updating the DP832 from firmware 00.01.16.00.00 to 00.01.16.00.02 I also configured the analog boards by doing the HELP-HELP-M4-M2-M1 and HELP-HELP-M4-M2-M2. Interestingly, the analog version went down a tick after that.

Before upgrading, the analog version was 03.02.05.03.02.05, but after the upgrade it was 03.02.04.03.02.04. It irks me a little bit.

[belzrebuth]

I also configured the analog boards by doing the HELP-HELP-M4-M2-M1 and HELP-HELP-M4-M2-M2.

Sorry but what's this?
This configuring of the analog boards I mean..Wheere did you find this key-pattern?
Is it mentioned in the manual?
I have a problem with my DP832 so it couldn't hurt to try it.

About your problem:
Could you try to downgrade the firmware and then redo the above?

You’ll find this key sequence in earlier messages, but I think I’ve seen it in older release notes as well.

I’m not really having a problem, just a little bit confounded by the version numbers, so I’m not going to downgrade again. Not unless I run into some problem down the road.

Hey guys,
can someone pls post the whole compilable source code for the 16M option? I am no coder and I tried my best, but i can not get this thing to compile. I would really appreciate any help

[belzrebuth]

What operating system are you using?
I could sent you an Linux compiled executable.

[Fabse]

Hello belzrebuth,
a linux executable would be perfect. I guess that's all I need
Thank you very much!

I have DP831 and I like to hack it to all updates. Where can I find the information?
Can I just use the DP832 - are they hardware wise the same or not?
Thank you guys!

DP831 and DP832 are different hardware but clearly the DP832 is based on the DP831.  I don't know for sure but I bet that the 'magic' USB stick will allow you to turn a DP831 into a DP831A but not a DP832(A).

[TurboTom]

It works for the DP811 so there's no reason why it shouldn't work with the DP831 which is much closer design-wise to the DP832 than the DP811...

[belzrebuth]

I think he means the model change command..

[TurboTom]

I used the "Magic Stick" to modify both my DP811 and my DP832 to the "A" version, so I haven't any doubt that it will as well work on the DP831 (to turn it into a DP831A that is). Maybe my previous post was a little confusing...
