Hello,
I will order a MSO5074 next week and I know that the fan is noisy.
Has anyone ever tried to replace it ?
Do you know what type of connector Rigol uses on this model ?

Thank you  :)

Hi,

https://www.eevblog.com/forum/blog/new-rigol-scope/msg1952305/#msg1952305

at 9min50s you could have a closer look to the fan.

If I wouldn´t be afraid of loosing warranty, I would build in this fan:

Are there any review videos or articles on this yet? All I see is Daves stuff and some things from Rigol/Saileg.

Does anyone know if the MSO5000 will fit the Rigol BAG-DS1000 bag?  Tequipment's dimensions do not distinguish between inside and outside measurements.  It is reasonably priced at $58 vs other, similar bags at $140 and up.

Hi,

I will order a MSO5074 next week and I know that the fan is noisy.
Has anyone ever tried to replace it ?
Do you know what type of connector Rigol uses on this model ?

In my opinion the MSO5000 is not noisy, at least my model in office. You can't compare it with series DS4000
oscilloscopes or waveform generators DG4000. The fans of these devices are an unbelievable impudence.
The popular series 1000z is little quieter then the series above, but loud enough in my opinion.
The MSO5000 ist not perfect with respect to the fan, but at least Rigol learnded a little bit. During the first hour
I hear sometimes a high tone, but then when the device has reached its working temperature there is only  a
little noise to hear. I guess if Rigol would have invested 3 Dollar more, we needn't to talk about the fan at all.
My recommendation: Buy it and test it for a while and think about replacing the fan if it is really annoying for you.

Hello,

Thank you for the advice. I ordered the MSO5074 with the front panel cover this morning so I think it will be at home friday or monday.
Im very sensitive to noise, I have mignaine attack very often so all my lab is very quiet.
I asked to Rigol for a fan replacement of my previous ds1000z and ds2000a model but without any success.
The only way was to send my scope to a reseller in Germany and pay 400€ for a silent fan replacement without loosing warranty.
On the other hand, Siglent allowed me to change the fan from my sds2204x that I always have :)

I will try to identify the fan connector if I need to change the MSO5000 fan.
I will let you know :)

As I wrote before, see Dave´s video.
It´s a 2-pole connector.

Is there a menu option to change to square graticules on the MSO5074?

Hello,

I watched almost every video on MSO5000  ;D

But a two pins connector means nothing to me, I would like to buy the right one to install a new fan without damaging the original one and be able to put it back in as original configuration.

Rigol NA got back to me about the goofy overshoots with some beta firmware that's supposed to fix it! (Temp firmware that's just toying with the fix).

Loaded the 5k now waiting on a self cal before testing. I was informed the new self cal takes care of the front end, and from what I'm watching that's the case. 7k test has to wait until a coworker gets back to me.

Edit: Got a chance to check the 5k. Square waves nice and flat now, with no funky over/undershooting or attenuation at higher f.

Answer, they don´t want it, warranty will be lost if doing it by yourself.

I wonder what was going on that it could be fixed in firmware.

It might have been some bad calibration parameter file, as a user reported not having the issue when using other scope's parameter files.  The unit I tested did not have the problem out of the box, so it might have had the good files.

Has anyone used PC software (Ultrascope or other) with the MSO5074. I'm most interested to know if there is any suitable Linux software that can be used with this scope. I assume the standard SCPI libraries that worked with the DS1054Z still work with the MSO5074.

Please see the thread here: www.eevblog.com/forum/testgear/mso5000-waveform-data-format-problem/
Ultrascope is windows only, but you could still use the web interface or python as above.

That'd be me. I checked out mabl's cal files to see what the difference was. They cleaned up the signal mostly, but skewed the high frequency response.

From what I can tell, Rigol added entirely new sections to the self cal routine to calibrate the rest of the front end. Not sure if this was simply omitted, or if they had assumed factory cal would be enough. Conjecture there though I'd think.

We just got in a few more MSO7ks today at work, and all showed the same overshoot until we tried the beta firmware + self cal.

I wonder if the overshoot fix is the only thing changed in that firmware... Mine now shows version 03.01.01.04.04.

Now, If only somebody were to share their beta firmware file for the MSO5000, we would know  >:D

MSO5074 on my desk right now  8)
Very good first impression. The touch screen is very responsive exept when playing with horizontal and vertical settings. It is unusable.
But enter parameters when playing with serial decoding, or setting trigger option for example is very usefull.

This feature will miss on my SDS2204X. I wonder if I will not sell it to go on an other touch screen oscilloscope. ( I need a scope at home and one at work ).

And the fan !! It's really a very good surprise.
It is much much quieter than my previous DS1054Z and my DS2202A.
The noise of the fan is not very pleasant, I have the impression to hear the fans of low-end PC power supply from 10 years ago but the noise level is acceptable.
I will wait some weeks before replacing the fan to be sure that the hardware is OK and destroy my warranty sticker  >:D

I like the layout....exept that the offset and scale settings are reversed compared to my Siglent  |O

Noisy fan....
Today I did some measurements, with TrueRTA and UMIK-1, SPL-meter calibrated (94dB).



Noiselevel before rigol was turning on:



After turning on:



Direct to the housing:



"Only" +5dB (first measure) but I swear, it sounds terrible... 8)

I don't know if you're ironic or not.

I was just saying in the message above that the fan noise was very acceptable and much quieter than my old Rigol oscilloscopes.
But the noise that generates the fan is not very pleasant as can be a Noctua or a Bequiet thanks to their premium components.

And that is a parameter that TrueRTA can't show.

No,
It wasn´t meant to you, today I got the time to measure it and I was a little bit surprised of how "less" the result was, although the fan seems to me so annoying loud... :(
Rigol plan something with the fan-"issue", they told me in the answer that warranty will void if you exchange the fan by yourself.
