Has anyone found a carrying case well-suited fro the MSO5000?

Rigol makes some:

How typical... major dejav-vu here.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Disappointing. Waiting for DS1054Z type maturity, then I may upgrade. Will wait until 2021 :D

DS4000 series was like that as well. I guess they are not entirely aware of the potential they have on their hands.

That or sheer incompetence.

I don´t expect monthly fw-updates from any one and none of the manufactors would do this - Still waiting for a bug to remove from our lecroy scope for nearly 2 years, another bug for a year.
And this one is a "serious" bug, not the little things what the mso5000 concerns.

You do realize that not all oscilloscopes are the same size, right? Rigol makes cases for some of their instruments. None are listed as being for the MSO5000, but digging further, none appear to be for instruments that have dimensions particularly close to those of the MSO5000. That's why I asked.

The bag you linked to is for a DS1000, which has dimensions 325mm x 159mm x133mm (DS1000B) or 303mm x 154mm x 133mm (DS1000E).

The MSO5000 dimensions are 367mm x 200mm x 130mm, so essentially the same depth but significantly wider and taller than a DS1000.

And they got a good reason actually(was informed).
All priorities lies on the launch of the 8000 series (very soon), after that, the fw upgrade will come.

Hi,
I've got a problem with this oscilloscope.
The heat on the back is very high and the front panel is hot too but not as much as the BNCs do (so hot !).
Dave opened the device and I've understood the problem : the internal fan doesn't not suck fresh air.
Why Rigol did not put the fan against the back side instead of inside ?

I'ld like to modify the device with a better fan place, model, fan duct...  but it's not possible without void the warranty.

To limit this temperature problem I've put a fan at outside of the back panel (see picture).
The fan is a 120mm low-noise model (Noctua NF-P12) powered with little 12V transformer.
It's pull the fresh air from the outside to the inside the device directly toward the internal fan.

The fan is fixed with little plastic wires and power is controlled with a global power strip button (oscilloscope, fan and others devices).

Now all seems to be good and not too hot.


Hope that could help you.

Always seeing black instead of white...Lecroy did the same, they told me the same as I did a request what the WS3000 concerns.
A normal behavior...

You must have a faulty scope.  I can have mine ON for more than 10 hours and the BNCs are at room temperature, no warming at all.

There are more manufacturers out there than Lecroy. Most of the A-brands can provide some kind of roadmap for releasing new software and / or have fixed release schedules. R&S for example releases a new firmware update for the RTM3000 series about every 6 months. 'When something else is done' is not a schedule. It is saying 'we don't know, we don't care and we have not assigned any resources'. It doesn't instill any confidence in me. I've been down that road before.

As a maintainer of software released at regular times, I can vouch for that as well.

In our organization, existing products have allocated resources from the dev teams to meet the planned schedule according to the software quality metrics previously agreed by the organization (or sometimes defined by an external agent such as ISO).

Having a new product in the pipeline sucking all resources and (supposedly) killing any hope for critical bug fixes and reaching the previously agreed release plans does not inspire confidence.

Obviously that I have absolutely no idea how Rigol runs their shop, but history shows they seem to bite more than can chew.

Mine is quite toasty especially the LA connector (55C) but the BNCs are fine. I wonder if they played with the fan speed settings at all.
May need to take a closer look inside in the future.

Hi !
I've found the same temperatures with DMM and a temperature probe.
I've tear down the oscilloscope and remove the original 80mm fan.
The fan voltage is 6.5V.

I've installed a 120mm fan and some foam to force the air flow to been pulled on the right and extracted on the left.
The LA connector drops 5C and rear air flow drops 10C.

I'm trying to find a better solution.

So we have 2 Month left.. ;)

After the mod mine is getting warmer too - But 55°C aren´t a value which would me make nervous.

Hi. I've bougth MSO5074 few days ago, and I had problems with overcompensation, so I could not compensate probes properly. After contacting Rigol support, I've received new firmare 04.01.04.04. Firmware solves overcompensation problem, and some others. So I think new firmware is on the way.

Before (01.01.04.04):
782736-0

After (04.01.04.04):
782742-1

782748-2

After tear down, i've done some additionnal pictures...

A new power supply ? (different from Dave MSO5000 review pictures)



My new proto airduct



Not purple, but green(+9V) and black(GND) (on the second connector, be warning of the second black wire, it's a +7V)
+12V = red(+5V) and purple(-7V)




I've tryed several fans...
- Noctua NF-F12 iPPC3000 PWM (3000trs/min ; 186.7m3/h ; 43.5dBA ; 7.63mm H2O)
- Noctua NF-P12 (1300trs/min ; 92.3m3/h ; 20dBA ; 1.68mm H2O)

Room temperature is 25-26C
The NF-F12 is too noisy even at 9V (analog input front end temperature is 33C)
The NF-P12 is correct at 12V but temperature at analog input front-end reach 40C (instead of 50C)
I'm waiting for another 2000trs/min model.

I've spent lot of time to analyse all heat sources.
I think the back panel and the original cooler system has a design flaw.

There's not a real airflow (left to right or front to back).

I'm trying to develop a simple 3D printed solution (or a cardboard solution) which could be easily build

Rigol> Why not create an efficient airflow ?

All priorities lies on the launch of the 8000 series (very soon), after that, the fw upgrade will come.

Although 8000 is basically 7000 with higher BW, i heard it will bring a few things that are not accomplishable with lower BWs.

And seems possible that they test the new bug corrections in the new 8000, since they are finishing it, and then replicate in the 5000/7000. The FWs look very similar.

Remember, we 5000 buyers have already been captured!
