I know what you mean...
Main reason for the MSO was buttons for each Channel and a bigger Screen..
And of course 350MHz BW with probes..
4  new 350MHz Hameg probes are more than half the price for the MSO...

So now is the question, is the Toellner analog FG & build in MSO AWG better than purchasing an additional FY6800?

Maybe selling the TOE 7401..?

I don't want to pay several hundreds euro for a sometimes used AWG only for the "Brand" Rigol/siglent ...

I think for sometimes in use and if you don´t Need amplitudes above 5v, the built-in awg would be enough.
And now I´m going to my siglent awg, blowing the dust away…. 8)

Got mine today.  Not seeing any real difference in screen brightness myself.

Mhh….
You compare it with another rigol…. ;)
Took my 5074 back to work for recording the displaying of PWM signals for the rigol support (actually I´m in touch with them, nearly daily - excellent support from rigol.eu by the way), I must dim the light on my desk to see everything on the screen almost bright.
But it´s not the most annoying thing.
On a friday afternoon none is here, I got my calm - And then switching on the 5074....The fan, god, only Lecroy Wavejets can "beat" it.
Rigol should allow customers the exchange to a silence one without loosing warranty…..

Either your under operating room light level or take off your sunglasses.

We´re wearing sunglasses since we got new LED Lights in our department... 8)

Seriously, the display isn´t the brightest one on the market plus the limitated angle view.

Ideal place for it is on the desk itself, in the shelf above it appears too dark.

Brightness might be controlled by a single resistor. Should be hackable.

At the cost of reduces lifetime :) but probably yes. Apearantly it runs at 9. something volt and the absolute max is 10.2 i belive

Don't worry, the people at Rigol already know the reason why they can't manufacture them fast enough to keep up with demand.

<5 because they keep coming out with a better hackable unit...forcing the hand to upgrade.

..least says the guy that dumped his crow for 1052, now three Rigols later.

Maybe it  musn´t be hacked.
Rigol have it on their to-do list(did a request About)..

Hi,

It isn´t really a bug, but today was the first time I used more than one math channel.
I took the low pass filter Funktion on three channels to filter out three phase sinewaves from pwm.
And they all got the same colour....
All 4 traces are violet - very irritating in cases described before.
Hope they´ll change it into 4 different colours.  :P

Hi guys,

I recently received my 5074. While trying to compensate the 10x probes, I'm unable to get the perfect square shape of the signal. On channels 1,2,4 I always get some overcompensation. On channel 3 it looks perfect. I've attached pictures to illustrate. Is it normal or should I return it, while still can?

Thanks!

The test signal on 'scopes is usually about 3V peak, you're only showing 300mV.

This makes me think you're doing something wrong.

Thanks Fungus, you're right! I had the attenuation set to 1x on all 'scope channels. I've set it to 10X, but this had no impact on the form of the signal. It's still with some overshoot on 1,2 and 4-th channel.

Have you tried swapping the probes to different channels to see if the problem is in the probes or the scope input?

I agree with TK; swap the probes around and see if the problem follows the probes or follows the separate channels.

After that, I would run the same test using a faster edge from a 50 ohm reference level pulse generator with and without the probes.

Yes, I tried swapping the probes. Nothing changes, seems it's the scope input. Also, when I switch the probes to 1x, the form is the same, maybe 30% less overshoot. I have no separate generator, but when I use the scopes internal, I get slightly different result, but never perfect.

I have very similar issue with my MSO7014, but in my case all the channels gives me the same result.
https://www.eevblog.com/forum/testgear/new-rigol-ds7000/msg2190588/#msg2190588

When tried with 50 Ohm input I got clean, perfectly compensated signal.
#nctnico suggested that this may be due to a crossover between LF & HF what kind of makes sense.
I hope that this can be calibrated and not something messed up on a hardware.

Just wondering if all MSO5k / MSO7k have similar compensation signal issue.

Thanks for the link! The issue seems quite similar. As I'm not quite experienced with 'scopes, it's not clear to me, shouldn't all this probe compensation thing be a simple, straightforward process? And what worries me is that I see the same shape with probes set to 1x.
