Hello,
So far I'm happy with MSO7k performance & functionality, but I'm a bit concerned of my device calibration and wondering is this something what can be fixed by a Firmware upgrade or I should be filling a warranty card for my brand new scope
I'm unable to get a perfectly flat 1k square with included passive probes RP3500A, I'm getting a small dip at the beginning of each wave.
Can this be a source of a small overshoot observed on a signal generator?
When I tried a DIY 1k probe on a 50
input with 1:20 attenuation I got a perfectly flat square wave.
Does anyone have a similar experience or can suggest if it's still in a acceptable error margin or should I be concerned and send it for a repair?
BTW tried to re-calibrate multiple times but this does not helped

I'd say that was due to the probing technique, nothing to do with the 'scope.

What does a piece of 50 Ohm terminated coax cable give you?

No.

I've tried to use a spring for my probe ground to minimise signal ringing on measuring signal from my integrated AWG what made little to none effect.
I saw very similar result (overshoot) on a different (external) signal source as well.
But the most important is a compensation 1k square wave which clearly shows a dip and can not be fully compensated.
This should eliminate an inductive loading from the equation as compensation signal ground is connected internally.
Obviously I'm not going to solder my probe tip to compensation clip for a better contact, but I did my best to make sure that it has a good contact.
Any further tips to try before concluding that either Probe OR Scope is defective?

What does a piece of 50 Ohm terminated coax cable give you?
As I mentioned I tried a quick test (1k 0.25W resistor directly connected to compensation signal & Channel 1) and I got a perfectly flat square wave. Then I'll have more time I'll make a bit more robust probe with compensation and parasitics taking into account. Differential probe would do even better. But my concern right now is about 1M ohm range / included Probes quality.
You can try a coax cable and a 50 Ohm feed-through terminator. A 1M input usually has various frequency cross-over points which need to be adjusted. Perhaps you are seeing the crossover between the LF and HF path of the 1M input. The 50 Ohm input path may be entirely different.
Nice device, but imho way too expensive, regrettably.
Hi there,
is there a way to get all the options and a bandwith upgrade up to 500 MHz for my DS7014 over a GEL File?
Use the same method as in the MSO5000 thread. Just need to craft the correct 7000 patch.
@tv84
did you have a workaround or how is the procedure?

I didn't do any patch for the 7000. If anyone wants to create the patch, I can provide the bytes to be changed.
Hello all,
something similar to the previous post, but not necessarily locking it to a GEL file: what's the best way to enhance
a MSO7014? (FW 00.01.01.07.01)
I read the "Hacking the MSO5000" forum, all of it.
Now, having the ssh enabled (root/root), I would think the -fullopt should be easiest way, and I can see in the "start.sh", line 82, the flamingo app being launched:
/rigol/flamingo_console $PowerOn -wpu_compress &
shall I just add the -fullopt there? Will it work?
Otherwise I don't think I have enough experience to create a GEL file myself to patch the app,
but I'll be happy to move on another forum ("Hacking the 7000"?) and provide assistance to someone more capable and create a tutorial for it.
Thanks

Sell it and buy a used DSOX3014?
(Sorry, I really couldn't resist the opportunity or, as we say in my home country: we lose the friend but don't lose the joke)
Too tired for reading so much. Waiting for a video review.
Just tested:
A fresh fully licensed MSO7000 with the latest v00.01.01.09.02 FW doesn't show any sign of working with the JITTER/EYE options!!
What a mega bummer!!!
Even the MSO5000 shows some signs of JITTER based on the MSO8000 developments...
Maybe this 7000 thing is dead and it doesn't even know it!
Bandwidth on a "opened up" MSO7000 using a Leo Bodnar fast rise time pulse generator 10Mhz (40picosec version):
First image of the pulse genny taken with acquisition set to average, measure set to normal mode, BW @250Mhz as you can see the average is just a shade of 1ns for rise time which would indicate a BW around the the 350Mhz mark using 2 averages.
Second trace as above with BW limit removed all other setting identical, now the result is 455 picosec rise time which is pretty close to around 820Mhz.
The 3rd one is a 25HMz rolling linear sweep, 500mV p2p.

Can you share resources for unlocking MSO7000? Do you have GAL with enabled SSH? Or if you have any patched GAL for MSO7000.
did you have a workaround or how is the procedure?

I would like to try to create patch for 7000. Please provide what needs to be changed.

Thanks to tv84, here is an happy owner of an "upgraded" MSO7014!!!
500MHz and all the options enabled!
I have the latest FW downloaded from the Rigol main website:
https://rigol.com/supports/software-firmware-download_3.html (Google Chrome is great to translate pages in Chinese!)
Welcome to the club actually you have pretty close yo 1Ghz BW as well Tv84 is rather good isn't he

I would say awesome, yeah!
Another big thumbs up to @tv84! I've got a fully enhanced DS7014 now, running the 01.01.07 firmware. Does anyone know if it's possible to "enhance" the 01.01.09.02 firmware?
Just curiosity, How is the web interface of DS7000 is like DS5000 a jpg image who refreshes very slow?
The MSO5000 and MSO7000 series are very similar in appearance and base firmware. The differences can be found in the larger bandwidth and better connector for the LA-probe in the MSO7000. The MSO7000 package also includes the LA-probes whereas this is an option for the MSO5000.
Compared to R&S scopes you will find the noise floor of the Rigol offering to be higher and some rough edges in the firmware for the Rigol scopes, but even the R&S scopes still contain bugs.
Both Rigol scopes are hackable.
