New Rigol DS7000

[nctnico]

Indeed but using the 0.45 formula would give a a greater bandwidth in retrospective so in essence stretching things a bit I feel!

No. Bandwidth is bandwidth.

You can also use a know signal frequency and amplitude as benchmark and work you work up the frequencies until you reach the point of -3db roll off this you can compare to the rise times to check you are getting for a correlation between the two methods.

Only testing with an RF generator yields valid results. Using the risetime is nothing more than an educated guess.

[maginnovision]

Yea, those coefficients are essentially guessing at the filter. That's why you go .45 for >=1GHz because it's likely brickwall. The real test is passband flatness across whatever you consider the bandwidth to be. A Rigol may well see an 870MHz signal but it's definitely not going to be flat or a nice roll off. It'll likely be up and down significantly more than the quoted bandwidth range.

[fact]

Measured the bandwidth of my MSO7000 with a RF-generator, -3dB frequency at 760MHz for CH1.
This was pretty close to the estimated bandwidth of 810MHz using a Bodnar fast rise-time generator.

[Martin72]

Didn´t really need an rf generator for my works and buying one only for measure once the bandwith would be too expensive.
They are some chinese things on the market for a few bucks (appx 120€) - But i think, they´re too crappy, or ?

[fact]

I used the tracking generator in my SAA3021x.

I have measured three via this means using a E4433b and they were all different, the best one I measured was 818Mhz @-3 dB the least was 787Mhz @ -3dB the bodar equated 830 and 870Mhz

The 8000 was reading 2.216Ghz@-3dB and 168ps on the Bodnar

The Wavepro254 measures 2.687Ghz@-3dB the bodnar reads 158ps on that scope

My MSO7014 is on my desk right now 

I just turned it on to see if everything was ok.
I was a little afraid of receiving a product already used because of the price but no, it is a completely new device.
I was also afraid for the bright screen but in my room, it does not seem to be a problem.

I go back to play a little

Did anybody try the latest FW 1.2.0.5 for the MS/DS7000?

FW link here: https://int.rigol.com/En/Index/listView/catid/28/tp/6/wd/7000

[jemangedeslolos]

I have the lastest....but i almost didn't use my scope with previous firmware.

What do you want to know ?

There are still some bugs I have to address but aybe you have a specific request ?

[wat]

Well, mainly if it possible to "enhance it" it as I did with the previous FW

[jemangedeslolos]

I can't answer you on this, I didn't apply the patch as I did on my previous MSO5000.

Jemangedeslolos:
I read you went for the 7000 series coming from 5000 series, what was the main motivation? I assume you hacked the 5000 to 350 MHz.
Was it possible to fully upgrade the MSO7014 to 500MHz?

I might be able to come across an used RTB2004 for 2000e but havent decided what scope to purchase yet.

[Sighound36]

HI Leon

A fully opened up 7000 equates to around 830Mhz, but it is a different animal to 5000.

I bought the MSO5000 while waiting for the release of the new Siglent SDS2000X+ so I knew when I bought it that I was not going to keep it for very long.
I wanted a full futured scope, with logic probes interface, active probe interface, big touch screen, separate vertical control, tons of memory and decent general performance for debugging, signal integrity and analysis during my HW and SW development steps.
I was sure to choose between the Siglent SDS2000X+ and the SDS5000X....But I came across a supplier that offered a brand new MSO7000 for a little less than 2000€ all included and it seemed like the best "bang for buck".

[jemangedeslolos]

Don't look at my post above, it is also because of Sighound36 that I switched to MSO7000 

[jemangedeslolos]

And I must say that I find that an used RTB2004 for 2000€ is very expensive unless it is full featured.
If it has no option, you might as well buy it new. I received a private message right here from a reseller who offered me 20% on the entire R&S range.

[Leon23]

Thanks both for your input. It is the RTB2004 fully featured for 2000e (rarely used). It seemed like a better choice than MSO5000 series with a more mature firmware and less bugs, 10 bit ADC and better display.

I am missing out active probe interface and possibly some megahertz, therefore I´m trying to see whether or not someone have successfully hacked the 7000 series :-). The SDS5000 series does also look interesting but cannot find if there is any hack available.

BTW what is the difference between MSO7014 and DSO7014, did the MSO series include the LA?

There certainly is if you hunt hard enough here.

The 7000 series is fully upgradeable via non purchase methods 

The mso does include a 16 channel LA probe

The 7000 has a larger screen better touch experiance, 10G/s sample rate and 500Mpts of deep memory it's a grown up version of the 5000 a nice user experience. The bode plot function is due very very soon as well for both the 7000/8000 series

We have the 5000, 7000 and 8000 Rigol models and use them every day we like them.

Martin72 made a very good observation regarding the 5000 its rough diamond and he was spot on it's just seriously good value with a plethora or options. It is being thamed nicely now

The 7000 is more refined, nicer user experience coupled with more raw horsepower plus a superb 500mpts of deep memory and 10G/s plus a genuine 50 Ohm  scope termination and probe recognition.

It also has the ability to perform multi domain analysis with its inputs which may prove useful as well.

hope that helps

It all depends on what you are looking to do. The RTB2004 is certainly a very good scope but it does not have much memory.
Full featured at 2000€, It sounds like a good deal anyway for me....But it's twice as expensive as the MSO5000. It's hard to compare these two.

The difference between the DS7000 and the MSO7000 is the 2 channel AWG and the logic probes interface. The probes are included in the package as well as the front panel cover.

At regular price, the SDS5000X is to consider.
All these scope are hackable, the only thing is that there seems to be old stock out there so we don't know which version of the front end we are going to have on the SDS5000X. So maybe you can hack it up to 500Mhz..or maybe 1Ghz.
And you have to add another 330+€ for the logic probes.

I let myself be tempted by the low price of the MSO7000 but at the normal price, maybe I would have chosen the SDS5000X.
If you are interested in that, know that the SDS5000x has a 10Mhz In/out that the MSO7000 doesn't have.

Can you eloborate a bit further on the use cases for which you use these oscilloscopes / what kind of work they are used for? Since you have also been shopping for a higher end oscilloscope I'm very interested in your opinion and experiences where it comes to the Rigol oscilloscopes.

[jemangedeslolos]

If ntnico buys a Rigol scope for himself, I think I can leave this world in peace. I will have lived everything.
As they can record data beyond the screen, nothing is impossible
