Rigol MSO 5000 hardware/software revisions

[luma]

So I've been holding off on updates as they didn't really impact me but this bode plot might be handy.  Has anyone tackled a patch for this release yet?

[NoisyBoy]

Sighound36, first of all, thank you so much for all your input on this topic.  I agree 100% with you.  Rigol needs a brand ambassador for all the reasons you stated, I think that could improve their goodwill towards the forum and that they value the user community's opinions.  It will only help them to be more successful and steer their firm to be more customer-driven.

I look forward to any further changes they have on the scopes.

tv84, great point.  I based my comment on using WordPress as the website editor, which gives one the flexibility to name the file to anything one wants, but their tool could be different.  However in the past, the downloaded file name always matched the version number, so there is a chance that it is an oversight in naming the download.

Hi,

It is currently a shame that Rigol doesn't seem to have ability to jump on the Tautech bandwagon of badgering the manufacturer into submission which seems to work for Siglent
As I have mentioned before Rigol need a brand ambassador with out jumping on ever thread to promote themselves  ideally a version of the Danny Bogoff show from Keysight with even more attitude  got to love that guy!

As I was in touch nearly every week with rigol.eu, we "discussed" this point also.
At least rigol.eu is not a big fan of this.
But they know the threads...

I have a few minutes to play with the Bode Plot feature, I cannot find a way to access it via the buttons yet, but it is in the application folder so it is easy to get to.

* The documentation has not been updated yet, and there is no on-line FAQ yet, so I have to fly blind.  Hopefully they will have something posted on the support site soon, currently the only help is the little picture on how to connect everything.
* The signal source seems to be locked into internal AWG Ch 1, the option to change it is greyed out even if AWG Ch2 is on.  So I don't have a way to change the source, perhaps if one attaches a compatible Rigol AWG via USB, the option could become active, I don't know for sure.
* With the internal AWG, the max frequency is 25 MHz, no change from the native AWG spec.

I will add more when I have more time to play with it.

Public forums are a double edge sword for manufacturers in that they give exposure to their products and their shortcomings.
Participation creates a higher workload and expectation to fix things that aren't right which demands good internal processes and higher cost impacting on profitability.

Still, IMO it is better to not have a paid company employee as the brand advocate as they are limited in what they say about products and still keep their job. None of us can influence a company direction very much as they each have their own agenda.

A bit more testing with bode plot.
I tryed an active 3rd order chebyshev filter. As you can see in the picture below, the gain looks as it should be, but the phase is ok until it reaches -180º, then it begins to increase instead of continuing descending . It seems that the algorithm just measures the instantaneous phase and doesn't consider the previous trend.
Anyway, this new functionality seems to be very useful.

Exercise for you guys with the new Bode plot...this done a couple of years back with the first Bode plot version in SDS1104X-E:

Simple Bode plot exercise/example.

1 KHz to 30 KHz passive band pass filter.
Components breadboarded from parts on hand.
Based entirely on the circuit example from here:
https://www.electronics-tutorials.ws/filter/filter_4.html





Should give us something like this:




SDS1104X-E
Sweep source SAG1021 optional AWG module
Connection HW; BNC cable and Tee, 2x BNC to croc clip leads (DUT IN, DUT OUT)

Sweep = 100 Hz - 100 KHz, 4V p-p, Low res

[pmaggi]

I tryed your excercise... different capacitors...
1,6 kHz - 23.4 kHz
Here it is the result...

[Martin72]

Wo-hooo, bode plot will come in may, they´ve once told to me - And now, it´s april, so early, wow...
Sorry, must correct this.
Will come in may is correct, but in may 2019....

Not bad at all.

Perhaps you could work some magic on LeCroy for a bode plot function as well

It seems that the algorithm just measures the instantaneous phase and doesn't consider the previous trend.

I wouldn't care about that. What I do not like, is that while "transitioning" from -180 degrees to +180 degrees it sort of averages the values. It first sharply starts transitioning for -180, but then smoothly comes in to +180.

Another thing that is quite funny (although not dramatic) is the "interesting" scaling for both phase and gain. Just not so... beautiful. :-) Rounding issues?

Another thing that actually annoys me a bit - while even less dramatic is the fact that apparently the only way to start the bode plot function is via the magic touch button in the bottom left corner. I kept looking for it in the measure - analyze menu. But there I wouldn't find it. It just gives once more the impression that this all is a bit half-baked.

But don't get me wrong, I still love this amazing device! It's just that they fail at such low hanging fruits! It makes me wonder how much they really test their products.

[Martin72]

As I wrote it before sometimes, my opinion was/is that the mso5k is a raw diamond.
It needs some polishes to become a "real" diamond.
Unfortunately, it lies on rigols hands only.

Another thing that actually annoys me a bit - while even less dramatic is the fact that apparently the only way to start the bode plot function is via the magic touch button in the bottom left corner.

The reason could be quite simple by not touching the menu structure at all, just kept it in the "magic button".

There is another way by using Measure button and in Analyze tab 

[NoisyBoy]

Thanks for finding it in the button menu, I did not see that myself.

I could and I would…

But as I know the support in germany well, I could say their forthcoming answer instantly now and here.

For those of you who have upgraded to the new firmware, new documentations are available:

* Manual
* Quick start
* Programming Guide
* Data Sheet

You can access them via https://www.rigolna.com/products/digital-oscilloscopes/mso5000/

You can look up how the FRA (Bode Plot) function work.  I was hoping to figure out how to let it use an external AWG, unfortunately, looks like the option is disabled and only the internal AWG is supported - for now.

If you want customization outside of the basic functionality they provide, better off writing your own SCPI scripts to control both instruments.

- HRESolution was added to :ACQuire:TYPE, but there is no mention of configurability. So nothing has changed there..
- :CHANnel<n>:POSition  command was added.
- :cursor:measure:indicator command added
- :search:count and :value added
- :trace command added (AWG)
- lower probe ratios added

Tons of small changes in the documentation.

Has anyone ever tried using a wireless mouse and keyboard set ?
I tried Microsoft and Chinese brand (Teknet) but nothing works.

Thank you

I use a Logitech M185 which works well; the tiny USB dongle thing has to be plugged into the front USB port of the MS05000, I tried a B-A adapter and plugged it into the back port but it didn't work.  I also found that the dongle needs to be plugged in before the scope is powered up (I think).

What's annoying is that, in order to use the front USB port for capturing screen shots to a USB-A thumb drive, you have to unplug the mouse adapter and you can't just hot-replug the adapter, the scope has to be power cycled to get it to work again.

[pmaggi]

I did it and it worked flawless.
You have to connect the receiver dongle before powering up the osciloscope in order to be recognized.

I tryed with a Logitech MK270 (just the mouse)

Seem that in the last fw. version 03, plug & play has been solved.
Also in Bode plot you can move the cursor by scroll wheel.

Thank you guys, I only did a quick test and I didn't think about rebouting the device.
I will buy a compact keyboard with a mouse and test by myself

You can buy a Logitech M185 mouse for about $20 but be aware that it's a bit smaller than a 'normal' mouse.

I already have some spare mouses, I will test with what I have but with the scope powered off this time.
What i wanted is a keyboard and mouse set to occupy only one usb port.
I also have a Logitech set with their "Unifying" dongle. If it works with that, I could choose any model 

Thank you again
